Creating your own panel for operator dialogs has a lot of advantages:

1) Most programs only stop when they are waiting for the operator.  You can 
inspect the operation of your program and probe lines while waiting for an
OK button in a panel.  This is not the case if you use VEEs message box. 
You can also change values of controls in inactive panels (although they
won't be read until that object is activated later.

2) You can select whether the panel is at a fixed position or moveable by
selecting "display on Activate" (for moveable) or Showpanel (for fixed)

3) If you have a lot of text to display (e.g. a multi-step setup
instruction), you can customize the display to make it larger.  I use a 2D
text array as an input, so I can view and edit the text easier.  For VEE
dialog boxes, the text often stretches beyond a screen width.

4) A high screen resolution like 1280 x 1024 is good for editing VEE code,
but it makes it difficult to see Dialog boxes when they are so small.  Using
a single userfunction with large fonts gives a consistent user interface. 
The alternative is setting the properties every time you create a new dialog
box.
