Hi Wojtek,
I'd be inclined to keep that hack in there for a while longer. It
isn't doing any harm.
Robert.

Hi Amalric,
Wojtek's workaround for the NVidia driver bug was only required for
XP, it wasn't required for Visita previosly. If you have problems
with wglMakeCurrent failing under Visita then this it's likely to be a
totally different issue.
To find out the cause of the problems you are seeing
Hi Robert,
no need to start a new thread I found my mistake, I was using a
osg::ref_ptrosgViewer::CompositeViewer
instead of a
osgViewer::CompositeViewer*
Now the wglMakeCurrent is working correctly.
I don't understand why ref pointer produce this kinf of behaviour, sorry to
flood you like

Hi Robert,
I use it and have not observed any issues. I would say its rather safe.
I reported this bug to NVidia. And it looks like they are doing something to
fix the problem. In the meantime they sent me two bit cryptic emails
informing they verified and fixed it. Last email was also saying
Hi Wojtek, thanks for clarification, I've gone ahead and merged the
workaround as it looks perfectly benign.

Hi Robert,
I've just reviewed your change and it looks benign, and I don't
foresee any problematic side effects on drivers that don't required
this double wglMakeCurrent() calling. The cost of wall
wglMakeCurrent() twice I don't see as something that is likely to
cause particular performance

I simply mean a test against the driver version, one could come up
with a who sets of tests that
try to isolate when this double make current is applied. Automatic in
as much as its a test that is
done within GraphicsWindowWin32 methods rather than something manually
invoked by the user.

Robert,
GraphicsWindowWin32 only exists under Windows, and given that make
current is so rarely called
and calling it twice with the same value won't break anything I'd
suggest we just integrate your
hack without any extra checks. As I mentioned before the extra checks
could well introduce
Hi Wojtek, Robert,
So I'd suggest merge your change as is. I was hoping for a bit more
feedback from other Windows
users before merging though...
You just needed to ask... ;) I tried the change to GraphicsWindowWin32
