Bug 68102 No mouse up when tree expansion indicator selected
Reported: 2004-06-21 16:42:31 | Status: resolved fixed

The Macintosh eats the up in this case, probably internally calling TrackMouseLocation() somewhere in the DataBrowser code. This manifests itself in Eclipse as 'single click ignored'. You expand a bunch of tree nodes and then single click on an item, it selects and nothing happens. Then you click again on the item and the selection action happens.
