Hello, Dear Sparky friends,

My name is Wen Chen, Im a post-doc from Rensselaer Polytechnic
Institute. Ive been using sparky
for a few years now. But today I had a major problem of sparky: I cant type any sparky commands using keyboard. Even I open a dialog window using sparky menu, I cant type or change any value in the window. BTW, Im using ubuntu OS.

Thank you very much for your help.

Wen
