Combo Lists extend off bottom of grid

I have a page with a grid that extends down to the bottom of the page.

In several of the columns there are AW.Template.Combo lists that contain several items. When the user clicks the combo dropdown arrow to view the list and to choose an item, the list extends downward, which pushes the page down further, creating a vertical scroll bar and an additional area extending off the bottom of the page.

When the user scrolls down to view the rest of the list, and then selects from the list, the popup list (and additional space it forced into existence) disappear, scrolling them back up to the bottom of the grid.

Once in a while this wouldn't be a problem, but if I have several dropdowns in my grid, suddenly the user is Opening a dropdown, scrolling down on the grid, scrolling through the popup list, selecting an item, being shoved back up to where they were before, etc.

Is there any way to swap the direction that combo lists appear, based on some function or other? If they are below halfway on the grid, they should align the bottom of the list with the combo textbox, rather than the top, which would prevent this scroll,scroll,select,jump,repeat that makes entering data excessively cumbersome to the users.

John,
Compare the bottom code on this post, with the original Popup template (ver 2.0.2 - I think) and apply the difs to the version you are currently using, then grab it on a page or a js file before call "new AW.Templates.Combo".
