Windows XP 
Access 2003
Hi all,
I just posted this same question to Rural guy in a reply to him after he helped me with another issue I had. I'm putting it here also so others can see as well and may be able to help me.
Like many of you, I want to disable the scroll whell on the mouth when users are working on the form. Now, I have downloaded several fixes online but recently I was able to get one to work until I realized that check boxes were enabling the wheel again as long as the checkbox has the focus, in onther words, if you click on any other field, the wheel is disabled once again.
So here it is, I have the code I downloaded in the "onload" section of the form, when it opens the wheel is disables and that is excellent, as soon as the user clicks on a checkbox the wheel is activated until he'she clicks away from it, can someone help me please, is there additional code that needs to added to what I have to prevent this from hapening. I have no coding experience what so ever but have gotten pretty far with my form and the company likes what I have so far. Here is what I have in the onload section.
