pressed, displaying the state of the INSERT key in a panel. It toggles
whenever the key is pressed, no matter which control has focus. However the
RichtextBox insert/overwrite ability requires that the RTB control has focus
when the INSERT key is pressed in order to change states. Therefore if the
INSERT key is pressed when the RTB does not have focus the statusbar INS
display becomes out of sync with the RTB's insert state, incorrectly
displaying the INSERT state of the RTB control.
I can't say I have experience with this situation, but I wouldn't say it's a
bug. You just have to code for it.
