I created a Impromptu 7.1 report with a dataset in the filter. The first time it runs normally, but after closing and restarting the report Impromptu crashes with an unexpected Windows error . Can anybody help me?
hello Wilfried,
impromptu 7.1, that is a while ago…, but never change a working configuration. 
Can you give more information about this problem?
like:
- do all data sets have this issue
- only this catalog
- do you get an error code when this occurs?
Wow - 7.1 dropped out of support a while ago. Still, as Admin says, if it’s not broken… 
The only other thought that comes to mind is whether your virus scanner is interfering somehow. Do you get the same issue if you disable virus checking?
