I' m running KDE 3.1.4 and as keyboard I have the US w/deadkeys activated to get german umlauts. I noticed frequent freezes in Agent when I typed new messages and now I know when it happens.
I have to press the ' or " key in order to get accented chracters or Umlaute. When I press this key Agent freezes, I can see a defunct wine prozess and I have to kill the wineserver. I haven' t seen anything on the console though. No errormessage or nothing.
Now I switched to normal US keyboard and, as you can see above, I can use these characters.
