After running a form, I check the path and it's ok, but then the next time I test a form, I get the error (sometimes).
IOW, somehow while I'm modifying a form, or a class or something else during development, the path gets chopped. The debugger won't catch that, because there is no prog() running.

>>Intermittantly I discover that my path has been chopped off to 256 characters.
>>I never put the path into a variable and then restore it later, so I can't figure out what's doing it.
>>My frmBase class tries to open a table that is located at the end of my path (in frmBase.Init()), so I discover this only when I try to run a form. By that time, I have no idea what might have done it. I've been developing since the last time the form was run.
