Using final cut express HD, the timeline and the canvas disappeared
I was using FCE-HD for an 8 minute video, and the canvas and the timeline disappeared (not sure if I hit any keys accidentally). I tried restarting FCE-HD - still gone; I restarted the iMac - still gone. I reloaded the FCE-HD software - canvas & timeline are still gone. I've looked through all online FCE-HD Q&A and haven't found a similar problem. I've been using the software for about two weeks - somewhat unstable with an occasional crash. I have Yosemite 10.10.4.
Thank you for assistance.
