Windows 7, 64-bit, Greenshot 1.1.5 Build 2643 (64 bit)
I took captures of the active window, and let Greenshot import them into Word 2010. The result of some dialog boxes shows like if there are layered, offset and transparent copies of the same window. It's only the outside of the dialog box, the text in the middle is fine (see attachment).
Thank you for the attention.
