[Wine] wine 1.1.40; Ubuntu 9.10; PowerPoint 2007 slow

[graviton]

I successfully installed Office 2007 with Wine 1.1.40 on my Ubuntu 9.10 but when I want to start the visualization of my PowerPoint, the window becomes grey and the slide show takes time to come.  As well as when I leave the slide show mode: the screen becomes black, I see the pointer but it takes time to come back to normal mode.  Someone could help me?

Thanks for your answers!
