I use Labview 5.1.1 to control A GPIB and A 3rd party frame grabber. I often get the error "Labview.exe has generated error...". I use NI-spy to monitor GPIB operation and found there is nothing worng other than the red line "viwaitonevent time out". However the instrument controlled by GPIB is working fine. The program crashes in random style and there is no specific error shown up before close window.
The problem is likely within LabVIEW and not your VI or the GPIB device. I recommend trying a different operating system or the eval for LabVIEW 7. You can also look into updating the drivers for your computer--ni 488.2, video, etc.
