MouseOver Problem when using a subform

[tobesurveyor via AccessMonster.com]

I have a form that has several labels that have mouseover events. When the
mouse passes over each, I turn on the underline of the label. When the mouse
passes into blank portion of the form, it checks to see if that label has an
underline and turns the underline off. This works great until I put in the
form a subform. It seems when I pass my mouse over the subform portion and
then back to the main form portion (over a label) it is not seeing the
labels until I click on the form.

Is there a work around to this issue?

thanks,
Chris
