Help! I am losing items!

[Kylar]

I'm afraid that items don't "vanish". If they have gone then player error is most likely to blame. Does anyone know your password?

I am sure no one has my password.

but if i have a 40 stack of X than that stack doesnt move in the marketplacewindow if i scroll down, so Y was never clicked. So though player error sounds most likely, I guarantee i cant have clicked it. I always move the mouse back to where the 'SELL' button is, so when i scroll down, i always hit it, and since scrolling from one row to another doesnt hit the 'SELL'-box below, i cant have clicked it.
And that's why i am so confused about them being gone. same thing with the armor.

which i just checked as i was writing this, is gone again!
