Miscellaneous: Zoning problem

[Jmich]

Hi all.

i'm having zoning problem.

it start loading but then nothing happens and programm doesnt respond. have to shut it down via task manager, and then i get error msg at login screen, have to wait for few minutes before i can get in again.

This doesnt happens everytime i zone, maybe like 1 time / 10 and it happens in various zones i tried, Halas/Permafrost/Blackburrow/Queynos hills.

any idea how to fix this ?

I'm using AMD dual core, ATI 4870 card, 4 gb RAM and Windows 7 32 bits.
Avast antivirus (tried turning it off but didnt fix the problem)
