I'm having an issue with DraftSight thinking every file on my local system is read-only. I can open a file on a flash drive or server, but local files are all locked. I have full permissions as a user and with all folders. DraftSight is the only program having this problem. I can open/modify/save any other file type with any other program. I use SolidWorks and DraftSight all day long preparing files for laser cutting, so having DraftSight being allowed to modify/save DWG files is critical.
