I might suspect the code, but if you didn't change it 2 months ago when you starting having issues, it seems unlikely to be the source of your problems.
If you are hosting your site through a company, I might ask their tech support if they might be changing the permissions on your files? I would guess an exernal influence is at work.
GreyMatter does actually try to chmod the files itself to determine if it can do so (weird huh?). If necescery I could post instructions for commenting out those lines of code, just in case GM is shooting itself in the foot somehow.

Yeah, this isn't too hard. Basically you want to follow the upgrade instructions in the install guide. The files you really want to make a copy/backup of is your 'archives' directory (or whatever it's named) and the following files: gm-config.cgi, gm-templates.cgi, gm-authors.cgi.
