Webtop RDP on Mac Problems

Hi all,

I'm not sure if this is the right category to post the question but here we go :

I'm an end user of a Web Top VPN with RDP as an published App. I'm using this from a mac book with 10.9.x OS on it. Once you click for RDP session launch – it goes full screen and locks you out completely. You cannot minimize the window (no option) or move away to another window to do anything. If I login via a Linux or Windows machine - it works fine but it's just mac which is giving problem.

Also the keyboard mapping seems to be a problem where my Command button on mac isn't giving me a Windows keys response like in Native MS Remote Desktop client.

Any help or work around for this would be much appreciated.
