Hello,
Can anyone explain what is happening, with Cubase 5, to make all my tracks (including vst drum track) disappear from the project window and mixer window simultaneously, like a row of dominoes, but in a split second? 
All I had done was press the ,< key to return to the start of the song. ‘CTRL + Z’ brought back one of the tracks so I checked the ‘EDIT’ menu and saw that the last action to undo was ‘Delete.’ One by one I brought my tracks back to the page, saved, and tried to return to the start to check everything still sounded ok, but the tracks all disappeared again. This time ‘Undo Delete’ worked for a split second but then the track repeatedly disappeared on its own. Looking at empty project and mixer windows I tried to find out what had happened by opening the ‘History’ panel and the only actions listed there were the 8 deletions in question, unresponsive to any clicking. I closed without saving but, when I opened the project again, I was still looking at an empty project window.
Before closing and switching off, I checked explorer and saw all the files were still in place in the project folder and, on rebooting, I opened the project from there. I have since carried on without a hitch, but nervously expecting disaster at any moment. I had previously had a few ‘CPU overload, Audio Drop-out’ messages (once when only 7 tracks of audio were up, before any FX or plug-ins were in action) and once got a blue screen crash.
Should I be worried about my hard drive or anything?
