Subj : TTreeView hints wrong when OpenGL context initialised

Hi,

My application has an OpenGL context displaying a 3d view in a canvas
window and a TTreeView which automatically displays lists of 3d
objects. The treeview shows tooltips (hints) for the TTreeNode items
if the width of the tree component is reduced by the user so that its
too small to read the full item names. When you hover the mouse over a
single item the hint is correct, but if you then move the mouse up the
list the hints are out-of-step. Also, if the TTreeNode items Text are
different lengths then black areas are sometimes displayed in the
hints.

e.g.

TreeView Items     Hints Displayed
Item 1             Item 2
Item 2             Item 3
Item 3             Item 4
Item 4             Item 4

Everything in alright before the OpenGL context in initialised but
afterwards its as described until the context is deleted. Any ideas
very welcome, I could override all the tooltips and manually set the
hint text myself but there definately seems to be a bug in Borland's
TTreeView hint code in conjunction with OpenGL.

Thanks,
Chris.
