Windows Vista Keyboard locks when I try to reply to BBS

Now I cannot reply to the posts which have been written to help me with my other two problems! The keyboard locks when I click "reply," and even stranger, I can't "X" out the BBS pages or any other Internet pages.

I managed to get this message posted by re-starting my computer, which for some reason, then allowed me to type a message.

Sorry I haven't replied to the desktop and script messages, but I get locked out!

Thank you, mattman. I have downloaded it and will see how things go. It was the strangest situation -- I couldn't "X" out any Internet pages at all, nor could I type a reply on this board...
