Adobe Connect Presenting for the uninitiated - help please

After last night I would really appreciate any hints and tips to make my life easier when doing presentations with Adobe Acrobat Connect.

How do I make sure that Connect doesn't suck the life out of my poor little AMD 2400+ processor?

Jeff Coughlin mentioned last night that I should have been using a lower resolution as there is a known issue with Connect and higher resolutions. So what resolution works best?

These are the kind of things I'd like to know as well as any other experiences you may have had that will help me and anyone else reading this give a better presentation first time.
