This has turned out to be a deeper problem than I expected. Due to the=20=

way initialization is done on GTK, the event message order with=20
PythonCard is different depending on whether you use the runtime tools=20=

or not when you start a sample or tool. What ends up happening is=20
'size' and 'idle' messages are sent before openBackground which defeats=20=

the whole purpose of openBackground as an initialization method.

I spent all of yesterday investigating this with Rowland and we have=20
some tests so that now I think we understand what is going on and might=20=

have a different way of doing openBackground.

We also found that on all platforms we are seeing a gainFocus message=20
for the first item on a Background, so that is a long-standing bug, but=20=

probably not critical because it isn't used much or at least not in a=20
case where it relies on prior initialization. The problem with=20
openBackground on GTK is more serious, so I hope to figure something=20
out for 0.7.3.1.
