Excel 2007 VBA - Can't type in VBA editor

[RagsdaleCT]

Hi,

I teach VBA and have a student who can't type in the VBA editor in
Excel 2007. He can switch to the editor & it displays fine. But if
he actually tries to type code -- nothing happens. Similarly, if he
adds an ActiveX control to a worksheet and tries to change, for
example, a name property he types away and nothing happens. His
keyboard works fine otherwise -- just not in VBA or the properties
window for ActiveX controls.

Any ideas? (He's already reinstalled Office once to no avail.)

Thanks,

Cliff
