I just saw something that explains a lot about reports that the copy and paste functions in the Sp@mX edit fields don't work.

I copied some text from one application (the font was huge), and pasted it to the Relay add edit window. Because the font was huge, I couldn't see the letters in the edit control, but they were there (they were added when I clicked the add button).

Then I copied some plain text from notepad to the same window (no font), and it worked fine (could see the text just as expected)!
