Vista - ElementHost resulting in black area before update

I have had problem with ElementHosts resulting in that they don't get
initiated correctly but only shows a black area until deselected and
selected again (the problem seems to be that the creation of the
graphics isn't done in time for the first display). I couldn't find
any workaround on the net so here is my solution which I hope can help
others.

My workaround has been used in VS08 beta2 and .NET3.5 and verified in
my project to some extend but I don't know if this will work as a
generic workaround.

The workaround
---
ElementHost e = new ElementHost();
[...]
System.Drawing.Graphics g = e.CreateGraphics();
g.Dispose();
---


Hope this can help someone else!


Kind regards
