Thanks for your reply, Eric.
I too set a breakpoint in my verifyText method, but the problem is that
it never gets hit when I do a shift+backspace. Doing a shift+delete
causes the breakpoint to be hit only if text is highlighted, which is a
"cut" command. I tried highlighting text, moving my cursor around, but
still nothing on a shift+backspace. It appears that verifyText does not
get called when shift+backspace is pressed for some reason.
Any ideas? Could this be a bug or am I just missing something?
