I'm not sure if this is a Drawing-specific issue, or not.
But, when trying to exit a drawing which I had already Saved, I receive the Save Modified Documents dialog.
Selecting Save All (or whatever that option states) seems to do nothing, and does not allow me to exit the drawing.
The only way I can exit the drawing is to select Do Not Save.
There was nothing open in Solidworks, except the drawing.
Did the Drawing not save when I did the manual Save?
Any info is greatly appreciated.
