New horizontal/vertical tab group problem when "Maximized"

Hi,

I'm working with an application which is using the Docking & MDI library in "Tabbed MDI mode", and I have found what I believe is a (small but annoying) bug when using the "New Horizontal/Vertical Tab Group" feature. The bug only appears when the application is "Maximized".

You can see the problem using the Sample Browser:
1. Start the "Docking & MDI" "Features Demo" as external sample.
2. Make the window "quite large" (without maximizing it).
3. Right-click the "WelcomeDocument.rtf" tab and select "New Horizontal Tab Group".
4. Right-click the "ReadOnlyDocument.txt" tab and select "Move to Next Tab Group".
5. Right-click the "ReadOnlyDocument.txt" tab (now in the new position) and select "New Vertical Tab Group".

The three tab-groups are now spread nice and evenly out in the workspace.

Now restart the "Features Demo" app, maximize the window and repeat the points 3 to 5 above. The tab-groups are getting smaller and smaller for each "New Horizontal/Vertical Tab Group" operation.

A workaround/bug-fix is greatly appreciated :)

Thanks,
Geir
