Trouble with saving .qsch files

Hi all,
I’m hoping this is just user error, but I can’t get QSpice to reliably save .qsch files. Files often don’t “appear” in Windows File Explorer, and will actually disappear from the File->Open function of QSpice. A QSpice upgrade (forced or a regular update) appears to “refresh” everything and make my files accessible in QSpice again, for a short time.
I’m wondering if this has to do with the file’s tracking of whether a file is modified before saving. Files appear to be saved more reliably if I actually make a change to a file before hitting “save.” If I hit save multiple times, without making a change, files appear more likely to disappear from access.
Am I doing something wrong here? Thanks for the help!

James
