Help~coherence does not work

I virtual my windows xp from boot camp with pd tools installed sucessfully.
But when I want to change my view to coherence,it does not work such as I never clicked the button.
Coherence is enabled in PD tools.
So I don not know what to do...


P.S. My build is 5608


Thank you for your advices~

 

First mind is to reinstall tools, using add/remove programs.

 

Thank you for your answer.
I've already tried,but it still does not work.
What others can I do?

Thank you~

 

Check in Windows device manager that video device is enabled

 

I checked and it showed parallels video driver and the video memory is 16mb.
In PD configuration display opition,I enable directx and custom display resolutions.
What can I do to repair my coherence display.

Thank you~

 

I mean check in Windows device manager in Virtual Machine, make sure that Video dvice is not disabled

 

I checked and it is enabled.
I also reinstalled PD,but it still can not work in coherence mode.
