Everytime, my Mac (OS X 10.9.1) goes to Sleep ("Ruhezustand" in german), alls opened Remote-Sessions are lost and the Microsoft Remote Desktop crashes. (i connected over a gateway).
This happens on my new iMAC with no other Software installed and it happened on my MacBook Pro with the last Version of iTAP. Seems to be a bug that is new since Microsoft is offering this application. Old iTAP-Versions worked fine with the same constellation.
