ResizeControlExtender causes panel to have 0px width and 0px height

All,

I am adding a ResizeControlExtender to a panel that already has a DragPanelExtender and am getting some very odd behavior. The window I want to resize is created dynamically and I add the ajax extender programatically as well. I am able to put a resize handle on the popup window but when I mouse over the handle the panel collapses to 0px width and 0px height. I have specified all of the properties as follows:

ResizableControlExtender resizeWindow = new ResizableControlExtender();

resizeWindow.ID = "timePanelResize" + i;
resizeWindow.TargetControlID = "timePanel" + i;
resizeWindow.HandleCssClass = "handleImage";
resizeWindow.ResizableCssClass = "resize";
resizeWindow.MinimumWidth = 200;
resizeWindow.MaximumWidth = 200;
resizeWindow.MinimumHeight = 24;
resizeWindow.MaximumHeight = 600;
resizeWindow.HandleOffsetX = 186;
resizeWindow.HandleOffsetY = 187;
dragWindowPanel.Controls.Add(resizeWindow);

I am using c#, .Net 2.0, AJAX v1.0.61025, IE 7 and Firefox 2.01. on mouse over the following behavior occurs; In IE it flickers and collapses in Firefox it flickers and the height collapses to the min height. Also, the handle is extremely difficult to grab... Also, the mouse must be in exactly the right pixel position (about 1px wide and tall) in order to grab the handle.

Anybody else see behavior like this? If so, is there a solution?

Thanks,

Kevin

There's an old forum thread about this, but the gist is that you add another Panel/DIV wrapper so the two extenders can point at/modify different HTML elements.
