Applications wont start

I installed OpenSuse 11.1 a week back and installed both Cairo Dock and Kiba Dock. But for some reason, whenever I double click on the application icons in “More Applications”, the window closes but neither application runs. I tried looking in the system monitor as well but I cant see it running there either. Could anyone help me fix this problem?
Thanks

Starting an application from a konsole can often give an indication of the problem.
