Has anybody else had this problem, it's driving me nuts..!!!
I'll be working on a largish site and checkout a load of files, (using FTP), then after a while Dreamweaver seems to forget the files are checkout. I can see the ticks disappearing from the files window.
This happens for no reason and then causes me problems when trying to update single pages or make global changes. If you are not careful you end up overwriting page versions you don't mean to.
I'm running DW CS4 under Windows 7 X64, and have a work colleague with the same problem under Windows Vista.
