On Windows, what could be creating these strangely named, locked versions of .doc files?
Every time I open a Microsoft Word 2010 document, it makes a second copy in which the first two letters of the file name are replaced with ~$. The Word logo next to the name is also fainter than the other documents. It's very strange, and when I try to open this version, which is always much smaller in size than the real version, a window that says it cannot be opened because of problems with the contents. I can easily delete the files, but it's tedious and pointless. Anyone know how to stop all this?
