I have the same problem in ExtJS 3.4.0. using IE9.
When I use the ExtJS examples, I also have this problem.
Steps to reproduce:
- Open http://dev.sencha.com/deploy/ext-3.4...x/msg-box.html
- Click the 'show' button for the confirm dialog.
- Move the window by dragging the top title bar.
Now the move cursor will still be visible, also when you move the mouse off the window, or on the 'close' button or something. Even when you push the 'Esc' button, the window will close but you still have the move-cursor. When you click, the cursor is correct.
- Not correct: IE9
- Correct: IE7, IE8, FF8, Chrome 15, Safari 5.1.2 (for Win), Opera 11.52
I've noticed that the same issue doesn't exist for Ext JS 4 Windows though, so does anyone know what workaround was put in place in Ext JS 4 to resolve this, as I need to resolve the same problem in Ext JS 3.4.
