Sorry, I am not running a Xara-capable system at present, maybe in a
few hours, maybe tomorrow. I hadn't thought of an error box; but if
you are happy with guesswork, then my thinking for several weeks has
been that lower level code was not reading a PNG, and that the bitmap
construction was failing. I was puzzled why IsOK( ) was returning true
on pSplashBitmap [and thought that this might be a weirdness in wx]. I
tried to put some TRACE statements into the AdvSplashScreen code until
I grasped the fact this was wx code and not Xara, and on my command
line system (which I try to keep close to 'official') I don't called
the AdvSplashScreen code at all - I couldn't fiond any way of doing so
safely, and I was fairly sure that the pSplashBitmap was faulty. (Also
wxWidgets even in the debug builds seems to miss a lot of
opportunities for sanity checking)

Working on the 'Xcode personal' system, that code is still in, which
is how I came to get enough information to finger the TLW constructor.

I suspect that when the hurly-burly is done, the root cause will be
found in the png to bitmap code still not byte-swapping, it would be
nice to have better diagnostics, but since I hope that these will not
be needed for long, I can't really make a case for spending time on
that.
