Hi, First post. I wasn't sure how to search for what is happening so if it has already been addressed I apologize. When I'm running Unbuntu 9.04 as the guest OS in Full Screen mode and switch back to the Mac desktop and then back to the full screen mode in Ubuntu, the open windows and browsers that were open in Ubuntu are all gone and I see an empty desktop. Anyone know why this happens and how to prevent it? -thanks. I'm using Parallels for Mac 5.
