I thought someone mentioned Explorer being very flaky and the desktop reloading. I've benn getting that also. If I hit Winkey e it may take 30 seconds for Explorer to open and another 30 to fill with content. Also if I click Explorer of the desktop often I get a disappear and reload. Firefox portable did run for me and connect to the web, but with Explorer like this it's really unusable.
I hope it settles down. I tried the 3 level defrag as recommended by VMware. Sped things up a bit but it's really touchy.
Edit: Please forgive typos. If I think the meaning comes through I may pass on doing 12 edits just to post 4 or 5 lines. After awhile it gets monotonous.
