Do not know what I hit in my learning fumbling around but clicking on the Files icon on the taskbar shows the little time spinner but file (explorer) never pops up on the desktop. I can get to it a couple of other ways and it works fine when opened from an alternative method. Just not how its supposed to work.
I was having lockup - time out or frozen - issues earlier when I had unplugged a USB headphone set to see how my speakers sounded for a movie that I was playing. Unplugging the headset threw Zorin in a right fine tizzy. No Task manager to see what but I had time to wash my breakie dishes, take a shower & put the trash out before I came back. Just as I was going to press the power switch it came back to life… BUT the next two commands - mouse clicks - one to shut off the video player and one to reduce another window from full screen each took about 5 minutes to process. Then it was semi back to normal but clicking on the Files icon doesn’t pop the window open.
I run Process Explorer on my MS machines that lets me override and kill apps without resorting to killing everything with a power shutoff. Anything like that for Zorin?
