.Net form controls drop by one "line" after selection
<p>Yes, I realize that's a bit of a vague title but I'm having a hard time stating the problem.  I have a .Net .aspx page that has a Master page, some Ajax, and an updatepanel.  My problem occurs on 2 different pages but in both cases I'm either selecting a radio button or a checkbox when the behavior occurs.  Immediately after selection the entire page moves down.  It does not scroll but instead it is like an extra <br> tag was inserted into the source.  I have done HTML source comparisons before and after this change and nothing is different.  I can only assume it is related to the updatepanel but I cannot determine where this may be happening.<br>
I'd be happy to provide more information if you can direct me towards a solution.
Thanks!</p>
