TextBox - special keys disabled?

[Guest]

hello!

i've got a strange problem with the textboxes in my vb.net application:

some keyboard operations seem to be ignored. that means that nothing happens
when i press the delete button. the user can fill in the textboxes with ascii
characters, backspace for example also works. but copy via ctrl+c or delete
per del doesn't work.

i made a breakpoint at the keydown event and it's triggered as normal. but
altough i don't change the KeyEventArgs member Handled to True, special keys
are ignored.

the problem may have some project-based cause, but i don't think, that i
have set some "global property" which disables special keys.

do you have an idea why this strange behaviour appears?

thanks, josef dabernig

the problem was that i assigned hotkeys to the menu in my applications.
disabling them solved the issue
