If I put a VirtualTree control on a sizeable form with a label control above it, the label control's painting gets messed up if you size the form down so that not all of the label fits.

I have the virtual tree set to anchor on Top, Left, and Right. So it grows when I size the form.

You can even see the painting mess up in the designer sometimes without running it.

There does seem to be an issue here. The problem is only evident if you size the form such that the tree control dissappears altogether - normally you would set the form minimum size to prevent this occurring.

Some preliminary investigation reveals that the problem is related to the use of the DoubleBuffer ControlStyle to provide flicker free control drawing. We should be able to provide a fix or workaround in the next minor release.

This has now been fixed in the latest release (V1-3-3)
