event handlers:

Absolutely. I try very, very hard to NOT write event handlers
that take a long time to process, but occasionally it is
unavoidable. In that case, you can be sure I turn the
hourglass cursor on before I enter the loop.

But I am also (knowing what I know about users) careful to
use the CLEAR_EVENTS keyword to WIDGET_CONTROL when I come
*out* of that loop! :-)

Cheers,

David
