WxMaxima doesn’t work under openSUSE 11.4. The problem is at wxGTK package. I filled a bugreport and now have updated it with solution.

This thread is supposed to help another users, and, above all, it should be pointed out to the maintainer of wxMaxima package in openSUSE team so he can update it.
(I am new to this forum, so if necessary move it somewhere else.)
