CS5 Mouse scroll up jumps full page

Question

I need some help. Just starting to use Flash but I've got this one issue that is just ruining everything for me.
When drawing on the stage, any upward movement of my scroll wheel scrolls the screen by at least half a screen width, if not more. Scrolling down works as normal, equivilent to a few lines at a time.
This problem seems to only exist in Adobe Flash. No issue in Chrome, Adobe Reader, Inkscape or any other program I've run. I've attempted to adjust the mouse settings, but they have no effect. Even disabling verticle scroll does not nothing.
Currently I'm using a Microsoft Wireless Mouse 6000 with Windows 7.  I've tried using other mice and they've suffered the same fate. I've also tried updating the drivers as well as cleaning them out and reinstalling them. Nothing works. I've googled and searched these forums but have found nothing related to this.
Suffice to say, its making using Flash impossible.

I FOUND A SOLUTION!!
After a few searches, this article gave a work around:  http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/mouse-scroll-wheel-not -behaving-correctly/84204cc1-097b-440f-ad16-aa92b6795465?page=1
Here is the relevant post:
my apologies -- I honestly didn't realize this was a non-technical forum.  To execute the above workaround (assuming the "built in" drivers...aka the HID-compliant...are being used):
1. Start menu -> in search box, type "regedit" and hit Enter (click through UAC security prompts)
2. expand down through...
     HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Enum -> HID
3. click around (expand the tree nodes) until you find a node named something like 6&xxxx that, when clicked, has something like Mouse or msmouse.inf appear in the Data column
4. expand to the 'Device Parameters' child node (of 6&xxx....) and click on it...you should see something like "FlipFlopWheel' appear in the Name column
5. [menu] Edit -> New -> DWORD
6. type in 'VScrollHighResolutionDisable' (no quotes) as the name
7. double click on your new DWORD and set the value to '1' (no quotes)
8. reboot, cross fingers, and retry your programs (if the programs are keyboard based, cross legs...just make sure to cross something....)
Microsoft probably has disclaimer text around modifying the registry by hand, but they also have disclaimers around using pre-release operating systems so you're already in unsupported territory (just don't delete or rename anything and you'll be fine).
in the quoted post, it says to look for something named "6&xxx".   I didnt find anything named that, so looked through each folder/subfolder (from top to bottom) until i found the first one to have a value of "Mouse" (in the data column) and applied the changes, and rebooted computer.
Hope this helps.
