When I make a screenshot in OS X using command+shift+3, my system becomes unresponsive for about half a minute.
I can move my cursor around, but that's the only thing that seems like it's alive at that point. I can click stuff, enter keyboard shortcuts, but it seems like they only get processed 30 seconds later, after the freeze.

My configuration is 2,8ghz MBP with 4GB RAM ... so this shouldn't be a problem, system-wise. (better performance setting in the energy preference pane)

This only happens when my system is running for a few hours though. But still, a few hours of uptime (less than a day) should not be a problem at all. I used to keep my C2D MacBook (Tiger) running for a few weeks and I noticed little to no decrease in performance.

What gives?
 
My Mac has better specs' than yours and it still freezes for a little while :( I think it's because its taking the screenshot but i'm not quite sure.
 
Huh. Bizarre.

I didn't really have anywhere to go with that. I was just curious as to what was going on. Maybe someone smarter can come up with a solution. :p

Yes, it is quite bizarre.

For people interested in this issue:
When using the command+shift+4 keyboard shortcut, the freeze duration depends on how large an area of the screen it has to capture.
Obviously, full screen screenshots are taking longer than little frames.

So it must have something to do with the processing right? And if it is, this shouldn't be the case on such a high-spec'ed machine ...
 
Could it be that your hdd is spinning down after inactivity, so when you take the screenshot there is a delay before it can write to the file as the drive is spun up again?

No, when connected to a power source, my MBP HDD doesn't spin down.
