I have posted a question in the Reports category, followed all the advices but still no luck. Here's my problem:
A small POS made with VFP5 replaced the dot-matrix printers with laser printers. Since then the application crashes all the time.

Example:
1. create an invoice and print it works fine
2. if I try to open the purchase screen the application crashes with the message "This application has performed an illegal operation and will be shut down" and the application name mentioned is VFP500.dll.

I thought that since the only change was the printers and since it works if I plug back the old printers, the problem is somewhere with the printers/reports. Maybe I was wrong because the crash really happends when I click the button that opens the Purchase screen and not when it prints.

These are things I tried but didn't help:
1. Cleaned Tag, Tag2, EXPR fields for all reports
2. Include/Exclude reports in/from the project

Thanks in advance for your advice.
