Works fine if you put

Application.Screenupdating = false

before your For. Sounds like you are over loading Excel's ability to update
the screen as your code requires it to refresh the screen over 13,000
times.....

Hello

I've been messing around with VB and managed to write a code which crashes
my pc, any reason why ???

I have a dual core 2.5 ghz, vista and excel 2007. Screen went white and
froze for 10-15 seconds.

Maybe someone else could try and see if it happens to them? Surely I
didnt
overload or confuse Excel with this;

For s = 0 To 65535 Step 5

Cells(4, 4).Interior.Pattern = xlSolid
Cells(4, 4).Interior.Color = s

Next s

Thanks
