I remember with the karma windows I had to use a trick where I used the tab button. I clicked the button, hit tab (so it would move to the 2nd text box, even though I couldn't see it) then I would start typing. When done, I't hit tab again and press enter (2nd tab moves to the 'ok' button)
you may have to press "down" or the arrow key to make it pick from a list. It goes in order:
Spam
warez or pirated software
TOS violation
Trolling or Flaming (I personally take offense to that. Not all us trolls are mean 
)
excessive language
other
You may have to press the down arrow to make it display the list, and possibly count the 'downs' if the list isn't visable.
