Doh! I kind of figured that you would have tried that
already, but you never know. OK... I have one other
suggestion– not such a no-brainer, but maybe more convoluted
than you want: VNC.
If you were running your app on another machine, it wouldn't
be able to intercept your keystrokes locally. I'm recording Mac
stuff, so I have no choice but to use VNC, but it's actually been
kind of nice.
If I'm just setting up a series of shots, I do it on the Mac,
and reach over and hit Printscreen on the PC as needed. That way,
only the clicks and keystrokes I actually want are captured. (And
if I mis-click, I don't have to listen to Captivate taking pictures
of me while I fix my mistake.) If I do want Captivate to detect my
actions, I work through the VNC viewer.
Have a great weekend!
