KSnapshot doesn't work if something is selected (for example, if I have selected a DropDown Box of a Program, the PRTSC/SYSRQ Button fails to work, or if a MenuItem is selected the button also fails!
WTF?!!

I want to take a screenshot of GParted while the upper right device selection DropDown box is selected.

How to do that?

NOTE: KSnapshot generally fails, if an DropDown Box or MenuItem is selected. WTF?!
Is there a 100% Windows-like PrintScreen Program for Linux??

bit more convoluted then one might like but easy enough

1) open Ksnapshot
2) select a delay, I use 2 seconds
3) click "take a new snapshot"
4) open the pull down menu you want in the snapshot
5) after the delay (they'll be a message on top left telling when to select rectangular region), highlight the region
6) double click in the selected region to initiate the snapshot (enter key is supposed to work, but only double click does in this instance for me)

thanks this works!

problem solved
