Thanks for your ideas everyone. I'm not sure I know how to relate the 
C++ code to Euphoria and specially Win32Lib. i tried setPenBkMode() but 
it doesn't really help. The setWindowBackColor() & setText() combo seems 
best as setText writes the whole area, and setWindowBackColor gives me 
the background I want. I have reduced the amount I write as a help 
measure and so far it looks OK. No getDC... failures in a while, but it 
always takes time. ...

Can't help wondering if there is a Windows resource freeing process in 
the background that can't keep up if you write too much too quickly?

Anyway, thanks.
