Excel 2003 crash

[Floyd Yeager]

I'm working on an Excel VBA project. I'm trying to interface with
another developer doing another part of the application. Since they did
some testing in Excel 2007, I'm having problems. The other programmers
file crashes and the repair turns all controls to shapes and loses the
VBA Project and macros. I'm Vista, they are XP, if that matters. Has
2007 corrupted the file for use in 2003? How can we uncorrupt? The crash
cannot be duplicated by the other developer.

Is the file, when worked upon in Xl 2007 being saved in XL97-2003 format?
It sounds as if it isn't.
