I have had several problems with Check-in and Check-out in windows 8. After moving the .mdb file to another folder, and changing DataBase tab, files seem to be check-in ok. But checking them out, I can recheck-in any changed files as many times as I want. It appears the changed files are duplicates in the project screen, but checking them out again, overwrites anything with the old, original files (no changes). The upper folder that was check-in to, has read-only writes and cannot be deleted, after check-in, until SVC is completely closed down and the read-only properties is changed. I thought the minor rev# would automatically change when check-in of a changed files, but it does not. It usually gives most files "skipped" then sometimes closes SVC after the dialogbox. I think I'll wait till this has been working on Windows 8 for awhile.
