I have at times lithose, but I haven't had it happen in awhile, actually I believe it stopped when I changed some settings in razor someone posted on the uoforever forums. Windows 7/8 wasn't out when razor was made so it can cause some issues. This will also fix any crashes you may have been experiencing too, especially when alt tabbing through windows.
Right click your UOforever shortcut, click properties, then go to compatibility tab, and check both "Disable visual themes" and "Disable desktop composition."
But yeah, they upped resist gain 10%, but its still painfully slow, only at 66.5 still and haven't gotten a gain in 200 casts.
