Vista - Mouse slow in HOST OS when VPC is selected?

I've been trying to find out why my new machine is acting strangely with VPC.
All the posts I've seen refer to the mouse running slowly in the GUEST OS
but my situation is different. The mouse runs slower than normal in the HOST
OS but only when VPC is selected or active.

I have a new machine made up of a Gigabyte GA-EP45-UD3R, Intel Q9550, 4GB
Corsair Dominator DDR2 RAM, a Radeon 8750 video card and a Logitech mouse
running on XP Pro SP3 completely updated as of today. All drivers are loaded
and running fine (no errors in Event Viewer and all software installed so far
runs fine). I have enabled hardware virtualization in the BIOS (also updated)

When I start up VPC (2007 SP1) the control panel is active by default as
it's got focus. As soon as it starts up, the mouse runs much slower than
normal. If I click on the desktop, the mouse is fine. This happens without
any guest OS even being started or created. It's just the VPC control panel
running.

Of course, when a guest is activated, the situation is the same and the
mouse runs slow in the guest too which is similar to other posts but in my
case the mouse is affected before a guest is even created. I have several
guests made up of XP, Vista, Windows 7, etc. and the issue is present in all
of them. However, it's not a GUEST OS issue, settings in the guest etc.,
since it happens with ONLY the VPC control panel. Virtual Machine Additions
are installed in all guests too though that's not the issue either.

So does anyone have any suggestions as to what might be the issue here? I
am moving off my old machine (Asus P4PE, Pentium 4 2.58GHz, 2GB RAM, a Radeon
9700 Pro video card and the same Logitech mouse on XP Pro SP3) where the
mouse works perfectly in both Guest and Host OS.

Thanks for the input!

Update: Sorry, too many numbers in my head these days. The graphics card in
the new machine is a Radeon HD 4870 1GB card, not an 8750. Though that info
is probably not the root cause of my issue. Still, I want to be accurate.

Well, in case anyone is listening, I found the solution on my own. It's not
a problem with VPC. Rather it's a problem with a setting in the Logitech
mouseware drivers I never ever touch.

In the mouse properties dialog under Motion, there's a check box that says
"Disable acceleration in games" which is checked by default. I just checked
my old PC and it's checked as it is in my new PC. However, in the new PC it
makes a difference when VPC is running. Clearly it thinks VPC is a "game"
and was disabling the normal mouse motion as set by the driver.

So, un-checking this in the settings restored the proper functionality to
the mouse when in and out of VPC when VPC is running.

Ta-Da!

Interesting, thanks for posting back! I had never seen that kind of
problem.
