I stumbled into the exact same problem yesterday: I could no longer drag n drop layers in the Layers Dialog. It happened immediately after a windows update updated my video drivers (AMD Radeon HD 6450), and although I hadn't realized it at that time, this is what caused the UI drag n drop problems in Gimp v2.8.6.
I discovered that when I re-installed the original video driver the UI problem was resolved, after having spent many hours re-installing Gimp, upgrading to Gimp v2.8.10, Installing and re-installing newer version video drivers for the HD 6450... then finally installing the ORIGINAL video drivers, and the UI problems disappeared. It would be nice to have the option of using up-to-date video drivers, so it would be nice to find out EXACTLY why this problem arises and find a resolution that will work with the new drivers. If any of you driver experts out there can figure this out, please post a reply. Until then, I will just keep hiding my windows updates for video drivers! I know better than to let my backups get behind and not be able to just do a full system recovery, which probably actually would have ended up taking a lot more time, but I was lucky to have resolved the problem by re-installing the original video drivers. When I get the system backed up, I will do a full recovery and install the latest video drivers and then install Gimp and see if the UI problem occurs. -- hmx (via www.gimpusers.com/forums) _______________________________________________ gimp-user-list mailing list List address: gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
