Taskbar pops up over Powerpoint when mouse on other machine

[Martin Stansfield 0]

Hi there. Forgive me if I am repeating previous threads. but wondered if this is a scenario experienced by others: Two desktop machines: [list]PC A (Windows 7 pro) running PowerPoint, (single screen mode) PC B running PowerPoint backup and VTs (also single screen mode)[/list:u] Synergy running beautifully, [i]but[/i] when I move mouse pointer over to PC B the Taskbar shows on PC A - on top of the PowerPoint presentation which is not good. Any thoughts, good people, what I can do to stop this happening?
