I was trying some agriculture, and started to throw firewoods to my field to burn the nice soil.
Area was big, First i threw them by keyboard.
Then I remembered that you can use mouse while aiming, so i did it. I clicked on my target (Red square was following my mouse, I know this worked earlier)
But now it said that message on my topic title. Every time i pressed a key, it said it again. Even when I pressed ?, it still made that message.
I couldn't save or quit propably, i had to close it by alt+ctrl+del.

I try that again soon to see if it comes again.
Version was 3.04-1

this is becoming a common bug, as atleast three people have reported it.
follow either the Minor 3.04 Bug thread and/or This Thread.

If Sami reads this, I suggest merging all three problems, as they have the same symptoms (keys not properly responding and game having to be killed via Ctrl+Alt+Del)

Fix is on it's way. Hopefully within few days.

This is why Sami is awesome. :D
