Hi Rick,
Just grabbed the latest DM build and am noticing that I am being prompted to save changes on application exit when I have not made any changes. (I actually noticed this with the version I just replaced.)
I open up DM and it opens the last project used, as expected, to the last topic opened. Without making any changes or navigations, I close DM via the standard Windows application close button. I am prompted about saving changes.

Yeah I see that too at times, but inconsistently. I believe it has to do with the document encoding - when the encoding changes the byte markers changes which changes the checksum. If you open a new project with older files it's likely the old files are encoded differently resulting in immediate unsaved changes.
However, it also seems to occur repeatedly occasionally but not all the time.
It's on my list of outstanding issues and one that annoys the heck out of me.

Clearly not critical, just a wee bit confusing at times.
I'll check it out.
I'm hoping to have the time to switch my team over to DM sometime in Q4. My primary documentarian, while quite capable, is not a developer/software engineer. She's managed to adapt nicely to WWHB so once I get my head wrapped around the git integration, etc I expect it to be fairly painless.
