When I try to share a document, it begins to share the document and actually starts the application. But, the pop-up message "Preparing document, please wait" never goes away and nothing further happens. I actually waited about 20 minutes the first time this happened. I can do other things within the conference, but the only way to get the pop-up to go away is to Leave or End the conference. The Nefsis printer appears to be installed correctly and is in the Administrators group. I am running as Host on an older (7+ years) Dell desktop with 2GB of RAM running Windows XP. Although I have been able to get this feature to work on a newer (2+ years) Acer laptop running Windows 7, it seems to take a while to bring up shared documents on that machine the first time. There are many advantages to being Host on the desktop PC, but I can work (for now) from the laptop. Any suggestions would be much appreciated.
