Hi, I believe the problem with this and VPCScreen is that KeyNote uses hardware acceleration to display the presentation. This means that although you see the image on the screen, software screen captures will not as the image doesn't exist within the operating system screen buffers.
The only way to avoid this is to disable hardware acceleration either within the operating system or within KeyNote itself (I have no idea if this is possible in either Mac or KeyNote).

The screen resolution was set to the same and I couldn't find a working solution other than to export to Powerpoint. I do see the Vine Server release notes (http://www.testplant.com/documentation/Vine%20Server%20Release%20Notes.pdf) indicate as something 'still to do': Add "Send Full Screen" Mode - Useful for things like Keynote which bypasses CGRemoteOperations API Possibly Detect when machine enters such a mode - ie starts running Keynote Not sure if anyone has any other work around, but other suggestions would be great., Todd On 11/12/2009 07:47 PM, Douglas Kosovic wrote: > Hi Philippe, > > Be sure to set the Keynote "slide size" to be the same as the screen > resolution set in the MacOS X system preferences, otherwise when Keynote goes > to fullscreen mode it'll change the resolution of the screen to whatever the > "slide size" is and I suspect confuse VPCScreen.
