Sticking keys, locking up sometimes

Hi there, I'm using the latest version of the enterprise client. Once in a while the UI freezes completely and wherever I click I get that exclamation sound from windows. If I click outside RDM I can use things on my PC just fine, and then I can click back on RDM and things get back to work.

Also several times I'm trying to type something and out of nowhere the RDM starts to issue commands outside my RDP window, so for example I'm typing something inside a RDP TAB and then the focus goes to my favourites list and starts going crazy all over the place.

This started to happen since the last update I installed a week ago I believe.

Thanks!
