Cannot Enter Time Machine
We have an external drive connected to the MacMini which we use as a Time Machine.
Time Machine runs and backups files as it should do. We can access these files directly on the external drive.
When running the time machine app to view the files nothing seems to happen. Finder opens a window (sometimes two) but none of the other Time Machine elements are shown. If we exit the window then a white horizontal box appears just above the dock for a second (like a graphics error) then everything returns to normal.
What's going on?
