This is frustrating me beyond words....

I'm building an excel based tool around a number of userforms and the
problem is this:

The user enters is password into a textbox, hits enter... and then the
numberlock switches itself off... I don't get it, why is it doing this?

It's annoying because you have to keep reselecting number lock and this
makes the whole thing look very amateur... is there some code I can use to
turn it back on, or am I doing something stupid that's making it do it in the
first place?

I'm using excel 97,

Thanks, in anticpation...
