[RESOLVED] Scroll Locking code and API is to turn on. (I need it to turn off instead)

The original version of this code turned on scroll locking, but I need to it turn it off if it is on.
I made the changes that I commented in blue, and it works as I wanted, but I want to have one of you experts look to see if you spot any other changes that should be made.

Thanks

afaik changing those lines would be incorrect, and are only effected in win 9x anyway
see if this helps you at all

Thanks westconn1

I certainly should have noticed that part was for win 95/98.

The link you provided I am sure I will find helpful some time later when I have time to sort through it to adapt it to my need, but for now I just modified the code I have. - I changed ScrollLockState <> True to ScrollLockState <> False and removed the 95/98 part of the code, changed the Elseif to an If for the NT part of it and am calling the macro in the selection change event. It seems to be working fine.
