Fransje,
Which LV version are you running? And what OS are you running?
I can't remember having LV crash because of a file open dialog. A run-time error, maybe but no crash.
If it crashes when you are browsing, there is definitely a problem somewhere. I haven't seen any problems on LV6.0, 6.1, 6.1i, 7.0 & 7.1..
Is the folder you are looking for hard-coded?
Although this one may not apply, I will still ask it: Does the directory exist?
Do you get an error message and an error number?
Are you running a vi from within LV or is it a LV executable?
Sorry for so many questions.. These will help us get on the right track to propose a quick solution..
Regards,
Ray
