Keyboard release event is not sent via RDP when the RDP windows loses the focus

[MVives]

Hi,
When accessing a VM via RDP, if you keep a keyboard key pressed and you lose the focus of the RDP viewer, the letter keeps autorepeating in the VM.
This bug does not happen when the same RDP viewer accesses a Windows computer with shared desktop enabled.
This bug also does not happen when we access the VM through the 'normal' way in VBox.

Configuration:
Host: Debian Wheezy
Guest: Windows, Linux
RDP clients used: rdekstop-vrdp, xfreerdp, rdekstop
VBox versions used: 4.1.30, 4.2.12, 4.3.4

Regards,
Manuel VIVES

Typo in 'VBox versions used': I tried with the 4.3.6 instead of the 4.3.4

The bug is also happening when I use the Microsoft Windows RDP client to access the VM

Please reopen if still relevant with a recent VirtualBox release.
