Hi Torquil,
I just ran your code on Windows and couldn't reproduce the "bug". Also
looking at the driver code I can't see, when and why the color of the
"pen" of the wxwidgets driver is set to another color. Apart from that I
would consider it good practice to set the color before I draw lines,
but nevertheless, I don't understand why there is a different behaviour
in Linux. I'll try to have a look at that as soon as I boot into Linux
again.
Thanks for the info.
Regards,
Werner
