Bob, I am not sure yet, but I think your code works.... OMG, I would really be up in the sky if this really works. I will test it on a client computer now (who has not yet given up yet... luckily..) Can you explain why vbAltMask is not what I want? I mean what is it good for if one cannot use it anyway? |
