I've used Ubuntu before, the Menu doesn't show up when passing the cursor on the upper window. About all that shows up is if I click on the upper window is a Menu to move the window, nothing else ... No problem, I went out to the garage for awhile & when I came back the Display was off.Nothing I did would bring it back up so I rebooted the PC back into Linux. To my surprise BOINC was no longer installed lol might be something to do with running it off the USB Stick. Anywoot I went back to Windoze, I just needed a little dose of reality on why I run Windows & not Linux ...
