I play Spiral Knights on Linux Mint 9 64bit in window mode
for some reason while chatting the character colon ":" just starts repeating on it's own whenever I chat...
the work around for this is to simply click anywhere outside the game window and click back in the game window again and it's fine again until it happens again
also during the period it's working sometimes I have to press the colon twice or three times before is prints colon ":" and that sometimes triggers the auto repeating character again
I experience a similar problem, but this one's when I try to use the in-game invite form. Whenever I get to typing the email address of the friend I want to invite, I press the "@" character and it just won't stop inputting that character. I can still exit the form by closing it, but once that happens, I get a few input glitches every now and then while trying to play.
I'm currently running SpiralKnights on Ubuntu 10.04 32-bit.
