Painting problem with Vista

Hello,

I have been breaking my head on the following problem all morning but can't figure out what's wrong.

I have a component that derives from TDBGrid but implements it's own painting function. The problem is that the component does not display the contents but instead only the colored background. This problem only occurs when I compile + run the application on Vista:

Compiling with D2007 on Vista and running on Vista:
The component does not display the contents anymore, but instead
only the colored background.

Compiling with D2007 on Vista and running on Win2000:
Everything OK

Compiling with D2006 on Vista and running on Vista or Win2000:
Everything OK

One thing I noticed was that when the problem occurs, the clipping rectangle of the Canvas is not correctly set but instead has a Top value of 35 instead of 0.

I hope someone can give me a hint on what to look for.

Regards,
