WoW 64 bit client error

[Alianka]

Hi,

since i installed 64 bit client for WoW, i get this following error every time i log in. It happens regardless if its clean install meaning with WoWRDX UI or with my UI and regardless if i have any other addon loaded or not. The only result of this error i get is that it quiete often, when switching UI states, does not repaint frames and do not want to repaint, but more often it just refuse to log saying its already logged and switched. And i tried and failed to make a sure way to reproduce it. It happens often when ExtraActionBar and with PlayerPowerBarAlt is needed. Switching back to 32 bit client solves everything, but i just happened to have win 7 64 bit ultimate, so want to use the whole power my PC provides .)
