(Italian version follows)
Today I tried to install ymol, a molecular visualisation and animation program for the X Window System, on my Ubuntu Edgy.
The compilation and installation was well, surprisingly when I launched the program i got a white windows, except for the title bar. To say the truth some parts of the window, in particular the menu bar become transparent. It was the first time it happened me, and I thought it could be correlated to Compiz. In fact when I compiled ymol on Dapper everything was OK.
