It's due to an architectural change we made in the internals of VEE. Because of the architectural aspect, it's surprisingly complicated to fix. That's why I'm not making promises about fixing it in VEE-NR: I want to see this one get through full QA testing before we announce it's fixed.</SPAN></FONT></FONT></FONT></SPAN></DIV><DIV><SPAN class=600373318-29012002><FONT face=Arial color=#0000ff size=2></FONT></SPAN> </DIV><DIV><SPAN class=600373318-29012002><SPAN class=778434319-29012002><FONT face=Arial color=#0000ff size=2>Sincerely,</FONT></SPAN></SPAN></DIV><DIV><SPAN class=600373318-29012002><SPAN class=778434319-29012002><FONT face=Arial color=#0000ff size=2></FONT></SPAN></SPAN> </DIV></SPAN></FONT></DIV><P><FONT size=2>Scott Bayes<BR>Software Technical Support<BR><BR>Agilent Technologies, Inc.<BR>815 14th Street S.W.<BR>Loveland, CO, U.S.A. 80537<BR><BR>970 679 3799 Tel<BR>970 635 6867 Fax</FONT> </P><BLOCKQUOTE dir=ltr style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #0000ff 2px solid; MARGIN-RIGHT: 0px">  <DIV class=OutlookMessageHeader dir=ltr align=left><FONT face=Tahoma   size=2>-----Original Message-----<BR><B>From:</B> Wills, Corey D   []<BR><B>Sent:</B> Monday, January 28, 2002 4:02   PM<BR><B>To:</B> ''<BR><B>Subject:</B> RE: vrf VRF: XY   object, problem with markes XY<BR><BR></FONT></DIV>  <P><FONT size=2>Attached is another example of this problem.  In this   case it occurs in an X vs Y Plot.  This example expects the two data   files to be in the root of the C drive.  </FONT></P>  <P><FONT size=2>There are notepads on the detail view of the user function   that give some specifics about where to look in the example and other misc.   info. </FONT></P>  <P><FONT size=2>I've seen this same problem with XY Trace (with single or   multiple traces), X vs Y Plot, and Y Plots.</FONT> </P>  <P><FONT size=2>Hope this helps the R&D people.</FONT> <BR><FONT   size=2> </FONT> <BR><FONT size=2>Corey Wills</FONT> </P>  <P><FONT size=2>-----Original Message-----</FONT> <BR><FONT size=2>From:   BAYES,SCOTT (A-Loveland,ex1) [<A   href=""></A>]</FONT>   <BR><FONT size=2>Sent: Monday, January 28, 2002 3:02 PM</FONT> <BR><FONT   size=2>To: "Vera Fernndez, Juan"; 'M Watts'</FONT> <BR><FONT size=2>Cc:   ''</FONT> <BR><FONT size=2>Subject: RE: vrf VRF: XY   object, problem with markes XY</FONT> </P><BR>  <P><FONT size=2>Juan, R&D has been able to duplicate your marker   positioning problem.</FONT> </P>  <P><FONT size=2>I am hopeful that we'll see a fix in VEE-NR, but as always   (sorry to keep</FONT> <BR><FONT size=2>repeating, but Tech Support doesn't get   to make the decisions about defect</FONT> <BR><FONT size=2>fixes) I can make   no guarantees.</FONT> </P>  <P><FONT size=2>Sincerely,</FONT> </P><BR>  <P><FONT size=2>Scott Bayes</FONT> <BR><FONT size=2>Software Technical   Support</FONT> </P>  <P><FONT size=2>Agilent Technologies, Inc.</FONT> <BR><FONT size=2>815 14th   Street S.W.</FONT> <BR><FONT size=2>Loveland, CO, U.S.A. 80537</FONT> </P>  <P><FONT size=2>970 679 3799 Tel</FONT> <BR><FONT size=2>970 635 6867   Fax</FONT> </P>  <P><FONT size=2>> -----Original Message-----</FONT> <BR><FONT size=2>>   From: M Watts [<A   href=""></A>]</FONT>   <BR><FONT size=2>> Sent: Monday, January 28, 2002 12:01 PM</FONT> <BR><FONT   size=2>> To: Vera Fernndez, Juan</FONT> <BR><FONT size=2>> Cc:   [unknown]</FONT> <BR><FONT size=2>> Subject: vrf VRF: XY object, problem   with markes XY</FONT> <BR><FONT size=2>> </FONT><BR><FONT size=2>>   </FONT><BR><FONT size=2>> Hi,</FONT> <BR><FONT   size=2>>    I have not seen any reply to this message - just   thought </FONT><BR><FONT size=2>> that you might</FONT> <BR><FONT   size=2>> like to know: I tried doing what you said with the example   </FONT><BR><FONT size=2>> file you sent</FONT> <BR><FONT size=2>> but I   did not see the fault.  Maybe you have a setup problem e.g. try</FONT>   <BR><FONT size=2>> making the mouse movement slower using the control panel   applet.</FONT> <BR><FONT size=2>> </FONT><BR><FONT size=2>> Sorry I   couldn't be more helpful.</FONT> <BR><FONT size=2>> </FONT><BR><FONT   size=2>> Mike Watts</FONT> <BR><FONT size=2>> </FONT><BR><FONT   size=2>> </FONT><BR><FONT size=2>> Message text written by "Vera   Fernndez, Juan"</FONT> <BR><FONT size=2>> >Probably this anomaly has   already been discussed in this </FONT><BR><FONT size=2>> forum, but   here</FONT> <BR><FONT size=2>> it</FONT> <BR><FONT size=2>> is.</FONT>   <BR><FONT size=2>>  </FONT><BR><FONT size=2>> The attached program   shows two traces on an XY object with </FONT><BR><FONT size=2>> the delta   marker</FONT> <BR><FONT size=2>> option enabled.</FONT> <BR><FONT   size=2>> I can move the two markers to any point of the first trace   </FONT><BR><FONT size=2>> (yellow) and</FONT> <BR><FONT size=2>>   they</FONT> <BR><FONT size=2>> remains there forever.
