SPACEROGER  Works fine. It basically sends a screenshot of your screen or active window to your co-worker. It would be nice to be able to send a note along, because I still have to shout my question or comment across the office.

Very simple but it works.

SPACEROGER  @FlashGen : In response to : "You don't appear to be able to define a region of your screen / just an application like you can in Snapz Pro"

In one of the demos on the developper site, you see that you can in fact crop a section of the screen after you recorded. I suppose they feel it give you more flexibility that way (i'll have to try to see if it's true, but it seem to be a nice way to build a good screencast)

SPACEROGER  NIce little software, it does simple editing easily, with a clean OS X interface, something you don't have in other sounds editors. Would be very usefull to remove gaps in mp3 for example (for those pesky "hidden" songs). Or editing some sound files before importing them to imovie.

I've had a few bugs however. The "wave" section disapeared once and I saw my desktop through! The mouse pointer changed with icons of the tools with no apparent reasons, etc. And I only played with it for a few minutes. Looks more like a beta to me, but something I'll watch evolve.

I'd be more willing to buy it if it was 20$ instead of 32, and once these bugs are corrected of course.
