Jumpy windows on startup

[MasterChief]

I have a small but annoying problem which I like to see fixed.

I'm using Ubuntu 8.04.1 (Hardy) 2.6.24-19-generic/x86_64 and VirtualBox v1.6.2

Now, it appears that VirtualBox opens or resizes like 3 or 4 new windows on startup before the WindowsXP/SP3 guest is running. I also keep moving the window to the top/left screen position, simply because I like it to be there on my first 24" monitor. Can this position be made permanent somehow?

And how do I stop VirtualBox from opening new windows (on startup) in different locations?

Here's what I do/happens:

1) click Start in VirtualBox to start the "Windows XP/SP3" guest
2) a new window opens
3) window moves to new position and displays: "Press F12 to select boot device" (*)
4) window moves to new position and MS Windows XP logo shows up
5) window moves to new position and resizes to target size (owner login)

* I have changed the 'bioslogodisplaytime' setting with:
VBoxManage modifyvm "Windows XP/SP3" -bioslogodisplaytime 0

This turned out to be limited to my setup with two monitors i.e. it does not occur when I use only one monitor.

p.s. No wonder I didn't get any replies...
