No, the taskbar doesn't disappear. What happens, if I'm using more than one document or file, and several webpages, when I go to bring them back up from the taskbar they just flash and won't open. It's odd because it comes and goes. It was doing it this morning for a while and then stopped. Very odd. This morning for instance I had two word pages open and when I tried to switch from one to the other they wouldn't come up from the taskbar. I went downstairs to have breakfast, came back up and they were working. It's been like that for a few weeks, started immediately after the last windows update. And the back arrows on all browsers don't work, but it's the same thing, sometimes they work, sometimes they don't. It's also changed the way I download. Sometimes it won't let me download to desktop, for instance, but that's all inconsistent.
