strange keyboard behaviour with TightVNC

Hi, I have SuSE 9.1 Pro, with KDE 3.4. I have enabled remote sessions in KDE. Now, from my Win2K machine, using putty to tunnel 5901 port, and after that ThighVNC as client, I see very strange behaviour - whenever I want to type "$" - dollar sign, I get "4". CAPS, Shift, nothing works. No dollar sign at all. This is the only key which does not work, all other !@#%^&*() work OK with Shift pressed, but not the $. It happens in every program I start under KDE, even in the terminal window. But, if I type it in the putty text terminal, it works. Any suggestions? Cheers Sunny
