This is a guess...

I think that the external BitBltPlugin won't load into an old VM due to the
version number checks that prevent loading of a plugin with a (major?) version
greater than the VM's (major?) version.
But having failed to load it, the VM doesn't then use its internal BitBltPlugin,
and keeps trying to load the incompatible, external one instead. Hence a blank
screen.

I think I should alter the installer to check the current VM version before
copying the BitBltPlugin into the executable dir.
The best check I can come up with (for Windows) is ...

    SmalltalkImage current vmVersion ~= 'Squeak3.7 of ''4 September 2004''
[latest update: #5989]'

Is there a better check that would also work for custom built VMs?
Cheers,
Andy
