[FIXED-26] Context Menu Misalignment
Ext Designer v1.0.0
When you right click on a component that is not selected. The menu will appear in the upper left corner (0,0), so I assume it doesn't know the component to get the position of for the menu.
BTW - I was testing the "select component" menu item. This is a joke right? Because the component is selected when you right click or left click on an item, so this feature is totally useless. Does it do something else, more clever, that I am not aware of?
This is one of these webkit bugs that's pretty annoying. We are working on patching the source.
This will be fixed in xds-220.127.116.11.
