Yes this only happens on my Druid, my shamans works perfectly... wow did crash a fiew times while boxing with my rogue as main toon, but not on loading screen.

yes both wow-windows load from the same folder, however this is not the same folder as I use when I'm not boxing. that to not need to change addons and stuff all the time. When i play on my "solo client" i have no problem logging on my druid so addons might be the thing. How ever I dont have any addons that I only use on my druid (on my boxing client), but I'm gonna try turning some of them off and c what happens.

thx for the tips
