Enhanced QT External

[Stephen King]

Hi Trevor,

Many thanks for the guidance.

I am working on it but noticed something odd happens as soon as a movie is 
loaded (also happens with the example Movie Editor). The Movie controller 
flickers continuously (though not playing) and processor usage rises to 
100%. Sometimes it recovers when focus moves to another window outside Rev, 
but it also seem to happen if I just add another control.
On saving, it seems to often (but not always!) run at 100% indefinitely.

I suspected this was a rev problem but I went back as far as Rev 2.2 with 
the same problem, so I'm now thinking its an 'XP' problem.

I have XP SP2. I have tried on two different PCs (different motherboards, 
different firewalls and even different versions of AntiVirus software) but 
they give the same effect.

Have you seen this before?

Cheers
Steve
