Buttons activating on form startup

[howieyo]

[Edit] Okay I think I know why it occurs and it is kind of silly haha. When they open the from the switchboard, they always double click on the the form to open and in the same position, there is the 'Flag' button...
So it registers the second click ...

I have a front end database that about 3 others use.
There is a form that contains customer's personal data.

It seems with 2 out of the 3 other people, when they open the student's form it always instantly 'clicks' or activates a button.
This never happens with me or with the other 4th person.

It has happened a while ago with a certain button that asks if you want to mark a customer as 'closed' (yes/no)


Over time I've implemented new functions, a button that asks if you want to 'flag a customer' for checking purposes.
So now when you open the form on those computers, it asks if you want to flag the student without you clicking on the button !

It's hard to troubleshoot this as it's not on my computer that it occurs.
Has anyone encountered this issue before? I'm just puzzled as to why it would only do it for certain computers.
