title: Scrollbar disappearing in IE7
body: <p>I have a div set to overflow: auto, max-width of 250px.</p>
  
  <p>Inside the div I have a paging control, which allows users to pull back 10, 20, 50, or 100 results. If they pull back enough results, the inner content (table) will grow larger than the div and should then be scrollable.</p>
  
  <p>This works fine in Firefox 3.5 and IE8, however in IE7, the scrollbar only shows after the first postback that requires a scrollbar (e.g. user selecting 20).  If the user then selects another amount that requires the scrollbar (50, 100), the bar in IE7 will disappear.</p>
  
  <p>If the user goes back to 10 results (no scroll needed), then proceeds to 20 results (scroll needed) the scrollbar will once again show up in IE7.</p>
  
  <p>I can still scroll the inner content with my mousewheel, there is just no scrollbar.</p>
  
  <p>Anyone know what the issue could be? I'm stumped... can provide details if needed.</p>
  
  <p>Clarification: The scrollbar is disappearing even when the content is overflowing the Div.</p>
