Is this possible? I only seem to be able to have one instance of RDP open as opposed to Windows, where I can open several. I find that quite handy - is there a way to do it on the Mac?
RDP for Mac is typical Microsoft half-hearted crap. For starters it will only recognise the \ character if you set your Mac to US keyboard layout, and secondly if you are refused a connection to a system, you are unable to type in another server name and connect without restarting the app. Utter *****.
*ends rant and pulls self together*
However, RDC Menu should solve your (and Sesshi's) problem. It launches multiple instances without requiring multiple copies.
