Hi Stephen,

I don't have a windows dev machine so can't test osgviewerMFC, the
best I can do is make suggestion for others to try out...

In this case if behavior is different between debug and release then
it will typically be either a thread timing issue or an unitialized
variable.  Personally I'd start with the later - go through all the
osgviewerMFC variables and check if they are initialized in the
constructors correctly.

Hi Miguel,

This is on a clean machine, and a clean installation, so it wouldn't
work unless I have the right libraries.

I have run this in Debug mode and whilst the first OSG window always
opens perfectly, and can be closed / re-opened as many times as I
choose.. any attempt at getting a second or third window causes an
unhandled exception which normally ends up with a return address
somewhere in 'Texture.cpp'.

(This then gives me a blank blue new window (if I continue running),
and the process in the previous window dies and stops rendering.)

If I shut them all down again, and it doesn't take out the entire app
then I can start again with 1 window without any problems.

The actual crash / exception that triggers this all appears to be the
return from msvcrt.dll, which I obviously cannot trace that easily.

But it appears to be a memory allocation / management problem at the
end of the day... as with all these things!

That's about as far as I can take it for right now unless you have
some idea? :-)

I have now twice downloaded and re-compiled OSG2.0 using the provided
MFC example without modification at all.

And I can run all other demos fine from the examples folder with this
build.

So I am totally at a loss for where to look right now...

Kind regards,
Stephen.
