Camtasia 7 problem in windows 7

I'm trying to make some free video tutorials for BHW, but i'm having some issues with camtasia.

I randomly get the error "The current color scheme, Windows Aero, is using most of its dedicated memory" and then windows turns aero off. I am NOT out of memory as I have 8gigs free.

Does anyone else have this problem? I've tried looking around google, but I haven't found an answer yet. Obviously, I could turn aero off, but I want to have aero turned on for my videos because I like the look of it.

Thanks

i think your video card drivers not installed properly or you should download camtasia portable version

here portable camtasia link

Does the portable version have all of the bells and whistles the original has?

I just switched to W7 from XP and would love to be able to use it

just change the theme to windows classic while u use camtasia and problem solved.
