2917.0. "Text insertion cursor dissappears" by ZSAZSA::READINGS (Richard Readings) Tue Jun 12 1990 09:54

If a text widget is declared with foreground colour = background colour after 
declaring a text widget with the foreground colour different to the background 
colour then the text insertion cursor dissappears for both text widgets.

Is this a known problem?

I will append an example as a reply (modified helloworld.uil).
