Just an update, Im still having the not responding issue, it seems to happen randomly at times, between both compupters. i thought it was to due with the shift key, but even after changing the keys the next day im still having the problem, im currently at work right now, but when i get home ill send you the id's and specs of the computers. I am using windows xp on one computer and vista on the other and I am also using Multplicity for using one keyboard and mouse on both computers. Btw this is happening with LoTRo, i have not tried it on WoW yet. The issue started with 1.8h for me as well, and carried on to 1.8i.
