Bug type: Visual
machine: x386 running redhat 6.2
LessTif 0.91.4, Xm-2.0 widgets
The problem is described in the comment of the example.
This is a bit of a problem for the application I've developed, as this
has a lot of TextF widgets, it creates a lot of windows that people
bring
to the foreground and background all the time. They quickly end up with
a lot of blinking cursors in several TextF widgets, even though they
don't have focus.
This problem doesn't show up in OpenMotif.

/*
This demonstrates a focus problem in LessTif 0.91.4
Start the application, put another window on top of it (e.g. an xterm).
Send this other window in the background using Alt-F3 (depends
upon your WM) so that your mouse cursor appears on one of
the TextF widgets. FocusIn gets called, but the window doesn't have focus!
Move the mousecursor to the other TextF widget, press Alt-F3 twice so that
the other window gets on top and behind again. Now you have TWO TextF widgets
with blinking cursors - but none of them have focus!
