CVI2009 general protection fault in user interface library commands

[jimc1965]

I have a program which we have been using and updating since 1999.  We have updated it in various versions of LabWindows/CVI and had no problems.  We recently updated it and compiled it in CVI2009 and now we get general protection faults.  The faults are occurring in commands from the user interface library and not always in the same command.  Sometimes it will process the commands properly and sometimes not.  PlotXY, PrintCtrl, SetMouseCursor, and DiscardPanel have each caused the faults.  Any suggestions?

Hello - 

My initial guess is that you are running into the issue described in this KB.  What is the version of cvirte.dll in c:\windows\system32?  If it is 9.1.0.427, you need to upgrade to version 9.1.0.428, which is linked in the KB.

Let us know if that does not resolve it for you!
