Jumpy mouse pointer

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Enable kvasdopager.
2. Start doing something, e.g. browsing the web.
3. After some time if not immediately the mouse pointer movement will become 
jerky/jumpy.
4. Disable kvasdopager the jumpiness goes away immediately.

What is the expected output? What do you see instead?

Smooth mouse pointer movement vs. jumpy mouse pointer movement.

What version of the product are you using? On what operating system?

It doesn't say, probably 2010.07.26 version. vwKvasdoPager.exe size 69,632 
bytes, vwKvasdoPagerBandWin32.dll 102,400 bytes, vwKvasdoPagerBandx64.dll 
117,760 bytes.

Running under Windows 7 Enterprise SP1 32 bits.

Please provide any additional information below.

It's not the mouse (driver) issue, tried with three different ones.

I see something very similar on Windows XP. Every time I do anything that 
accesses the file system, the mouse pointer motion becomes very jerky. It seems 
that something is eating 80% of the mouse events for about 10 to 15 seconds  
every time I open a directory. I am using the latest versions of Virtuawin and 
kvasdo pager. I do not see this on the Win 7 machine.

I see the same behaviour in Windows 7: enabling kvasdopager and the mouse gets 
very jumpy, diabling kvasdopager makes ist smooth again. Funny enough, I had 
the same setup working for the last year or so and I like kvasdopager very much 
and would like to continue using it. 

One other observation: on my system, a service from PGP Desktop, PGPtray.exe is 
also running. Disabling that and continuing kvasdopager, the mouse stays 
smooth. So at least in my case, it looks like it is an interaction between 
kvasdopager and PGP Desktop.

Same behavior here. Also on Windows 7 SP1 32bits with PGP running.

I believe this is the same bug as Issue 34. The trick we're using to support 
changing desktop with the mouse wheel is causing slow down.

I posted a patch on Issue 34 but it never got in.

Posting here again with a build for testing. If you're affected by this please 
try this version and see it helps.

The changed is part of vwKvasdoPager.exe so be sure to replace that and not 
just the DLL.

No jerky mouse issues for me under Win7-x64-SP1 using the attached 
vwkvasdopager-issue34-build-2.zip build.

Yes I noticed that unusable usage of the jerky mouse as soon as I started 
VirtualBox virtual machines, in my Windows 2008R2 VirtualBox Hypervisor.
With this patched package: vwkvasdopager-issue34-build-2.zip
all is working smoothly now

So many thanks to alexandre.jasmin for this patch

This problem started happening to me as well after I purchased the USB 3900 
from plugable to use with my microsoft surface 2. After removing the older 
kvasdopager and installing the new *-issue34-build-2.zip it worked perfectly.

Thank you alexandre.jasmin!!
