Since I'm using the cropping feature quite often, I have noticed a minor bug with the Crop button on the toolbar. Here are the steps to reproduce it:
1) open an image
2) press F to enter in Full Screen mode
3) select a crop area using mouse while in Full Screen mode
4) press F again to enter Window mode and the Crop button becomes inactive for some reason. The "Shift+X" hotkey works fine though. And also, clicking on the crop region using left mouse button (or pressing F two times) - activates the Crop button.
Hope this minor issue will be fixed in the next version

And thanks again for the software!
Anton.
