This has got me stumped!
I have searched help, online and here, and I can't work out how to do this.

With a tool like SnagIt, you can simply use a region editor to copy or cut an area and paste that area in another location. It's really quick, you draw the rectangle around the area and then you can just drag it to a new section.

I want to be able to select a part of a photo or bitmap and cut and paste / drag it to another area.

Any ideas how to do this quickly and easily?
Thanks!
