I have three machines that have out of the blue no longer minimize AccPac 5.3 to a smaller size on desktop. They either display full screen or shrink to system tray. The only way I have been able to stop is to reformat whole Hard Drive, simply wipe out of AccPac from C:\ and registry will not work. If I log user into another machine there screen settings return to normal. This is resident to machine and I have no idea how it starts but once it has I can only fix with complete rebuild any ideas??
