Dear Jon,

Thanks for your support.

The first not (it always happens when two monitors are connected)
The second could have to do with this, yes. This is the procedure:

- Start XWin, docked, working with it.
- Undock, going to standby, SSH session may die
- Wake up without docking (only internal screen)

Now all windows are shown on the (non-existent) secondary screen if I
open new X programs.

Also, I can't even close it because even the Exit Prompt is hidden.

> Does restarting XWin after dock/undock still show these problems?

Yes, if I kill Xwin via task manager.

[ LAPTOP ]     [ External Monitor ]

When docked: External is primary, Laptop is secondary screen
When undocked: Only laptop exists, so this is primary now.

Laptop: 1366x768
External Monitor: 1920x1080

Thanks,
Lukas
