Using SU4S on windows 10 PC and a chromebook. Saving all my files on google drive. SU4S is creating a duplicate file every time I click “save”. I tried turning off auto-save. It still creates another file every manual save. Worked about 1 hour, saw I had 10 files, all with same name and same .skp extension. Only difference was what time file was created. Any ideas? thanks. m.
