Issue with shift clicking / attacking in place?

Hey all,

I'm having some issues with shift clicking items out of and into the stash/inventory. I can manage one item with the shortcut, but if I hold the shift button down it no longer works?

As for attacking in place, that works the first time I do it as well but POE doesn't seem to recognize that my keys are being held down? My keyboard works fine in every other situation, it just seems to be this one place that's giving me some trouble.

Any help is much appreciated!

Thanks!
