JDesktop JTextFields stop receiving input after ALT+Tab

When using a JDesktop with input-fields (typically JTextField), these stop receiving input from keyboard after the user have switched application by using alt+tab, (jME in window or fullscreen mode does not matter).

Anyone found any solution to this? its kinda annoying not being able to use input-fields.

Old thread with partially the same problem:


Update: If you press the alt key once when the inputs are locked, you will regain input functionality

I have the same problem, but with the mouse and the IE. In another Browser works fine.
