Popups cease to work after zooming

Actually after some poking around, I found that it's very difficult to reproduce this problem in a consistent way. Sometimes popups do come up, sometimes they don't. If I zoom out a few times and mess with other things on the map (other popups, etc.), the missing popup might start to appear again. Sometimes zooming in doesn't stop the popup from coming up in the first place.

Just a thought, but may be related to:

OL.Behaviors.popupClosed = function(event) {
  // @@TODO: Currently the feature is not unselect when the popup is closed. This function should do that.
}

in openlayers_behaviors.behaviors.js

Actually, after more poking around, I think it has nothing to do with zooms. Sorry for the white noise. I think it has to do entirely with the fact that features don't un-select when you click the red X. I wasn't testing very cleanly.

Here's a patch that automatically unselects a feature when its popup is closed. I gave the OpenLayers.Popup.FramedCloud constructor a callback for when popups close. The callback calls SelectControl's unselect() function.
