Well that last test was without Prat installed. So inconclusive at this time .. wow that sounded fancy
I'd say, if it is resetting more often than not, its worth a try. Most of the time I just use Prat for the font changes only. Before 3.2 I think it was because of the extra functionality that is now in WoW normal.
Try it out for a while and see if it seems to solve your problem.
