For the last several weeks whenever I click to either minimize the window or exit the program -- I have a stand alone version -- a small Mcaccess message window pops up with "This program has performed an illegal operation and will be shut sown. If the problem persists, contact the program vendor...MSACCESS caused an invalid page fault in module KERNEL 32.DLL at 0157: bff 99dbd. Registers...." This latest time I just opened the program long enough to open one of my marriage files in the preview window to see some data. I had planned to add some entries a few minutes later so wanted to keep clooz open - minimized - which saves me a lot of time compared to how much longer it takes to open it. Can someone help solve this problem - and mystery - for me? Thanks in advance for your help. -kay thesarge
