I've just upgraded my 12.10 to 13.04. The only problem I have right now is with scilab.
After the upgrade, scilab doesn't start correctly: the software starts but the graphics are strange, and I'm not able to move or resize the window and click on the menu.
The problem is related to Ubuntu 13.04 because I've tried every version of scilab and all show the same problem.
Can someone point me in the right direction? Thanks
