We are facing the same problem at out department. One solution we found, is to delete the complete directory
c:\Documents and Settings\username
After deleting this folder, windows had to copy the default profile to the users profile and afterwards the
Labview problem didn't appear any more.
But in the end the bug isn't solved yet. Maybe anyone at NI can look for a solution. We have traced registry and disk traffic, but since there are quite a lot of posibilities of error causes, someone who knows exactly what the program does might have better luck than we had.
Since this way worked for us it doesn't really make sense, that a graphic card driver problem is the cause. Other apps doesn't show that behaviour.
Good Luck
