Hi Laura.
I have a VFP 7 application installed at several sites. Fatal Error/C0000005 errors are occuring frequently and always on the following line of code:REPORT FORM (filename) TO PRINTER PROMPT PREVIEW
The only time that I have ever seen this behavior is when VFP did not like my printer driver. However, since you have switched to text only, this seems a little unlikely in your case.
The next likely suspect is the TO PRINTER PROMPT clause. I realize that you want allow the user to selected the default printer and number of copies before printing, but what happens if you remove this clause? If removing it gets rid of the error, e-mail me and I will send you a report preview formset class and custom toolbar that gives you this functionality without using the TO PRINTER PROMPT clause. It works with my framework, so you will have to modify i slightly, but it should work for you.
