Bug in Megawizard of QII10.1 Linux version

[Altera_Forum]

I have installed QII10.1 on Ubuntu10.04. Everything works fine except the Megawizard. 

When I use Megawizard to customize some components, for example, a 2-port RAM, the page will not change when I click "next" button. Though the caption of the window shows [page 4/5/... of 12] correctly, the content of the window remains the same as that of page 3.  Has anyone else solved this bug? Many thanks!

When I customized PLL with Megawizard, it worked well.

This megawizard doesn't like the desktop visual effects. If I turn them off then it runs normally.
