The following problem occurs in NT 4.0 under IDL 5.0.0. I haven't
tried the program on other platforms. I have a program which repeatedly
updates a LABEL widget on a base widget several thousand times. It
basically just writes out pixels which it has processed.
Also there is a make-shift percentage status bar which gets updated
regularly. After the display has been updated about ( don't laugh )
14,232 times, the widget locks up.. nothing more gets displayed.
The percentage bar's "bar" disappears much earlier.. but the text
display in the draw widget continues to update for the entire life of
the widget.
All operations continue to take place behind the scenes and the run
actually does go to completion. When the run completes, the entire
screen corrupts. Windows flash around and makes things generally
un-usable. In some cases I can use the task bar to close the run away
widget and recover, however in most cases I have to reboot.
Has anyone ever experienced this kind of thing before?
Thanks, Matthew Sheats
