Version:           4.6 (using KDE 4.6.4) 
OS:                Linux

I am using VirtualBox as VM runing other operating system.
I activated the auto hide mode for the panel (containing the K-menue an other widgets) to get more desktop space for my programs.

If I do so and let run VirtualBox in full-screen-mode I can not use the little Virtualbox-panel that used to appear when you move the cursor to the centered botton of the screen.

I actived the always-visible-model of the KDE-panel I can use the VirtualBox-panel when I run it in full-screen-mode.



Reproducible: Always

Steps to Reproduce:
1. KDE-panel is on bottom of the desktop
2. set the auto-hide-mode for it
3. start VirtualBox 
4. start a VM 
5. put the VM in full-screen-mode
6. position the mouse cursor in centered botton position

Actual Results:  
the VirtualBox panel does not appear

Expected Results:  
the VirtualBox panel should appear
