N5242A, PrintToFile method seems to cause spike in delay

We have a VBScript that is executed as a macro on the network analyzer (N5242A).  Among other tasks, it is supposed to print the screen to file once an hour.  During the time that this macro runs, the analyzer is in continuous sweep mode.  Once the printToFile method runs, a glitch (spike) in the group delay measurement can be seen.

I'm waiting to hear what the exact firmware version is from the team, but the analyzer is running at least firmware version A.10.00.00 (running windows 7)

We're fairly sure it's related to the PrintToFile method, as when that line is commented out, the behavior does not repeat.

I've attached an older (but not substantively different) copy of the macro.

Thank you very much for any assistance.
