Mouse over menu bar => software stops working

[HOW]

Hello,

when the mouse cursor was placed over the menubar during startup of my
application, the software stops working.
The same problem occurs when the software shuts down.

Environment:
- WinNT SP6 or Win2000 SP2
- MeasurementStudio 6.0
- Visual C++ 6.0

The application was written in Visual C++ 6.0 (no MFC) using the
CVI-Librarys.

Thanks in advice for help
Hanno

Hi Hanno,

If you are using InstallMenuDimmerCallback(...) and entering some type of infinite loop, you may see this behavior. If you are not using this function, please provide a more detailed description of how to create a project where you see this behavior. Did this project show the behavior from the beginning? Was this a conversion of a CVI project? Did you use the NI Measurement Studio AppWizard to create the project?

If you can give me more information on the problem you are seeing, I may assist you further. This is not a problem that has been reported previously.

regards,
Eric

Eric,
I am having this same problem. My application is in a loop polling a piece of hardware via RS232. Once the mouse pointer enters the menu bar, it stops processsing the loop. Once the mouse pointer leaves the menu bar, it starts processing my loop again.
I do not use InstallMenuDimmerCallback(). THis project was created in an earlier version or CVI but has been upgraded to 6.0.

I have the same type of issue and it has only happened since an update to 5.5 was applied and all version 6.0 runtime stuff I have written
