Mac + Multimonitor + Remote Desktop access = read only on second monitor

[Pau Garcia i Quiles]

Host: Macintosh 10.6.3 (this issue is not reproducible on Windows or Linux)

Guest: Windows XP SP3

Steps to reproduce:

1. Configure multimonitor (in my case 3 monitors, but 2 should be enough to reproduce)

2. Enable multicon (VBoxManage modifyvm WinXP --vrdpmulticon on)

3. Boot the Windows guest

4. Connect to the first display (@1) using the Remote Desktop client (this issue is not reproducible if using multimonitor through VirtualBox GUI windows), start an application and move a window partially to the second display.

5. Now connect to the second display (@2) using the Remote Desktop client and try to move the window.

Result: you cannot move the window, it's like the Remote Desktop connection to the second display is read-only.

Expected behavior: you can move the window. VirtualBox 3.2.0 on Windows and Linux does not have this problem.

You can use any Remote Desktop client to reproduce the issue. I tested on Windows 7, Mac (using Microsoft Remote Desktop Client 2.0) and Linux (rdeskop 1.6.0).
