Hi Phil, Check fonts and printer drivers. Had an instance where new fonts installed on a system broke apps. I automatically now delete any font file over 1 MB ;-). Also printer drivers can cause issues. An example is a customer where everyone could run an published app except for people whose default printer was a Canon 3-in 1 printer. Other possible areas are the wrong version VB DLLs, and occasionally a DLL that is missing. ListDLLs (www.sysinternals.com) on a working system (even a normal desktop, can give you a clue.

Basically, I've got an app in which every time I go into it and try and open a file, it crashes out with an application error saying the referenced memory at xxxxxxxx could not be read. I've run filemon and regmon, but with no luck, so was wondering if any of you could point me in the right direction!
