The weirdest error - SP 2 known error???

[Dan Ardelean]

I posted a few days ago a question on firing KeyDown
events for Buttons using SP 2 - not avaible anymore. Can
somebody explain the weird behaviour of the code attached
at the end of this message (if you have installed SP2)??
If you paste the code and run you will get a form with one
button. When the button has focus the color is red. If you
press the cursor buttons while the button has focus it
will show a message with the cursor key pressed and
everything works as it has to. Now simply add (with
designer or any other way) another button to the form and
try running the program again. When I tested the fired
keycodes and sequence don't make sense. Is this a known
bug in SP 2?

Thanks:

It's best to revert to SP1 - don't know the full bug list, and people
probably never will, but as it was recalled just forget it existed...
