Environment:
Windows Vista Express C++ 2008
Short History:
CMAKE and built my own binaries.
osgText sample didn't work - Rebuilt FreeType => Happy days.
Take my project from 1.2 => pretty involved (for this 'bear with a little
brain') => databasePager, geospecific terrain, HUD, Picking, etc
Wouldn't compile -> Update my mouse handler via current osgPick specifically:
use 'new' osgUtil::LineSegmentIntersector::Intersections::iterator
Happy Days.
Except it looks like on the first mouse-over that should send text to the
screen I get:

Sorry if the above is word-wrapped into mess :(
So I basically cut and pasted code from the 1.2 examples into my own project
and tailored them to fit. So the mouse-over code - the rubber hits the road
with a call to 'SetLabel' which in the current osgPick is simply:
if (_updateText.get()) _updateText->setText(name);
Well my version is currently:
dynamic_cast<osgText::Text*>(dynamic_cast<osg::Geode*>(_MainDisplay->asGroup()->getChild(0))->getDrawable(0))->setText(name);
I have two HUD's - one to be a popup and the other remains visible at all
times. The mouse-over text is to show in the always visible or '_MainDisplay'
HUD. So this is my (perhaps insane) way to show the contents of 'name' on the
screen in a mouse-over sort of fashion.
It seems the first call fails consistantly.
I have found that if I set a breakpoint on my dynamic_cast ...... line, then
remove it and run - that it'll work for awhile.
If I break everytime is seems to work.
So any help on work arounds etc? Fixes? Pointers? I would be happy to send
my current code, but I doubt that anyone would want to put in the investment in
wrapping their minds around my insane code. It may be related to the
aforementioned threading problem.

If so - please let me know and I'll stop pulling my hair out.
Thanks.
