Why does Labview hang when switching between frames in block diagram?

[trosier]

I changed the name of my global vi which meant I had to go into my top level vi and make the necessary changes there as well. All was done and I saved everything. Now my vi opens fine and I can change to the block diagram. However when I try to change to certain frames within the block diagram Labview hangs and I have to use task manager to close it. What is going on in this case?

What do you mean by "frames"? What LabVIEW version do you use? How long did you wait before using the task manager?

It looks like something got maybe corrupted. Can you attach the problem VI?

I am using Labview 7.1 base version. I wait until about 10 seconds which is when task manager says Labview is not responding. By frames I mean frames of a stacked sequence structure. The thing is none of my VIs that I use within my main program will work either, including ones that had nothing to do with any global variables. I am leaning towards the corruption thing as well. I am currently reinstalling Labview to see if that fixes the problem. I hope it does as this VI that I have has taken a while to develop. After I made all of the changes and everything worked ok, I backed it up. It was only after I closed it and tried to run it again that this problem surfaced.

First, delete all the temporary files (normally it is located in c:\documents and settings\username\local settings\temp .
Second, try a force compile on the VI.

All - Thanks for the help. Reluctantly the only thing I could do to fix this was to reinstall Labview. That fixed the problem. I am a little concerned that I had to do this just from the subtle change that I made to my VI in order to get this to work. However, it did fix the problem. Again thanks for the help.
