Did as you instructed Pyro.
My results:
Click on the "Copy" and a window does pop, but is all white and freezes immediately.
CTL+ALT+DELETE shows Aces High "Not Responding".
I also experimented with changing the Windows compatibility to anything other than Windows 95 and each of those would freeze up even before I had a chance to click on an online arena.
I just tried a regular program open and the little "wooden" pop-up that asks do I want to give the new version access through my firewall and it lasted for maybe .3 seconds before it disapeared and the arena choices came on. Call me crazy, but it seems whatever was done on the latest version did something to short-sheet the amount of time one had (presumably until they made the yes or no choice) to click a choice. Now, for some reason, and on some peoples PC's--not everyone's, it only shows it for a fraction of a second--disapears--and then the online arena choice clipboard is there. That might be a chunk of the problem right there.
Turning off my firewall completely did not solve the issue.
Again--I am disabled and have days open. You guys have my email and I can send you my cell. I'd be happy to help if it can solve the issue for those who have it.
