I have the strangest problem. I've been working on this app for a while now and every now and again MS access will cause a corruption that requires me to remove all the modules from the startup form save the form and them paste them back in. I usually do a Cntrl 'A' and then a Cntrl 'X' and paste them into a blank note pad window. The corruption stops the Startup form from doing anything when it opens and does not process any of it's events (i.e. On Load, Open , Close). This usually happens while I'm running and working in the .accdb format. But now this has changed. Every thing works fine in the .accdb format, but when I complie into an .accde format the non responsive forms problem returns. And it's all the forms; none of them will execute any modules. I've tried my usual cutting and replacing code, I've even started a whole new database imported all the parts and test it and it worked, but as soon as I compiled it, the compile version does the same non functioning forms thing. Now I do have other .accde apps that are still working so I don't think it is access its self. Any other Ideas. I'm running Office 2007 ultimate (64 bit) on windows 7 .
