"Scrub" Button

[FalvinP]

I have just downloaded the free version and have been playing with it for a few hours now. I'm using a PIII 533 Mhz machine with Win98se. I know this isn't the best configuration to use with this, but other functions seem to work, although some work slowly. The scrub function intrigued me. However, when I press the scrub button or the spacebar the computer freezes up and I have to push the power button and reboot. It won't let me use ctrl-alt-del...it's really frozen up.

 

Does anyone know why this is happening?

 

I like what I've seen so far. I will definately consider getting the upgrade.

 

Thanks for your help.
