Thanks very much for this. The crashing with 3 connections open was driving us crazy.

I have only one more small issue with this version, and that's the fact that the first (Default) panel is hidden from view if it's the only one used, until a new one is opened.
This causes resizing of the sessions in that first panel.
I'd very much appreciate the option to enable mRemoteNG to show the first panel by default as well, just as it was in the earlier versions.
