things in .vbp file changing case every time they are saved

Why do some references stored in a vb prioject file always change case? Is there anything to do to prevent it or does anyone know why it happens? The attached file is a report of a "diff" I did between my code and what is on source control, so you can see what I mean. The problem is, if I let it save, then the next time it will want to save in the opposite case again, so this cycle continues over and over again.

The problem I have with this is, that when I go to source control my files, I can't just select the whole bunch to put on source control, I have to do a diff to see what changes are "real" changes, and which ones are just these ridiculous case changes, and it takes a lot more time to do.

Thanks,

Yeah, I see the same things on occasion when I commit to my CVS, I've yet to figure this one out. VB has some quarks about the case of names, I've just always ignored it. If I can find anything that trigers it, I'll post back here.
