In full-screen slideshow mode, Powerpoint has the wonderful feature to draw on the screen with Pointer Options Felt tip and Highlighter.
Especially useful if you have a touchscreen or drawing tablet.

Unfortunately, this feature is not availabel when running your powerpoint in windowed mode through a 'set-up your slideshow' config.

I really need to run my PPT windowed, but need drawing tools as well.
Any suggestions?
