I know one thing. The upgrades sure don't like Widows 7 with IE 11. I have been viewing the forum since I joined in Dec. 2013 using IE and windows 7. Now I can't post replies or answer PM's plus everything is way over size. Borrowed a computer to post this. Guess I'll just be a read only here. I'm sticking with IE and win 7 because it is still compatible with all the other forums I visit and its easier for me to navigate back and forth between sites. I know, got to go with progress.
