Hello, I'm using MS Office 2007 Pro on Ubuntu 10.04 x64 through wine-1.3.17. After a while my laptop will just freeze (like someone took a screenshot) when I have multiple PowerPoint windows open. This problem seems to be only associated with PowerPoint and not the other Office Apps. Also, whenever I minimize the PowerPoint windows they will group together on my taskbar but little gray square boxes appear on the top left hand side of my screen. It takes a bit of clicking around to get a different PowerPoint window to maximize after it has minimized as well. Any help is always greatly appreciated.
