Scroll Lines

I am having a weird issue, I am trying to get finer detail when scrolling with my mouse wheel or any mouse for that matter, but it is scrolling too many lines at a time. I have been researching this issue all day and found that I can reduce the amount of scroll lines in windows to 1 however, it is still scrolling 2 at a time. I am not sure if this is a windows problem or a parallels quirk but either way is really annoying.

The biggest issues is when I scroll in Microsoft Visio. When holding control and scrolling with the mouse wheel you can zoom, however due to the wrong scrolling lines the zoom increments are unusable. Can anyone help shed some light on this issue?

Thanks.
 
I have been having this problem ever since I switched to Parallels from VM Ware over a year ago. I have periodically searched for solutions and waited for updates to fix it but nothing yet. It is extremely irritating as visio is the main program that I need this to function properly. Not having good mouse control for navigation is slowing me down too much and affecting my productivity that I am now considering using CrossOver to run Visio.

I plan on testing it this weekend and will report back.
 
So, here is what I have discovered and done so far. First, I replaced my mouse with a Logitech M525 because it has what they call a fine tune scroll wheel. But an increment is an increment in windows irregardless of the nature of the scroll wheel clicks. After much research and trial and error here is what is working the best. If I run windows in full screen mode the up/down scrolling is 'better' not great. It is still scrolling by twos. However left right scrolling and I assume CTRL-scroll (zoom) are jumping 3 at a time. This is not very useful. I am going to try next messing with the registry as it seems to be completely ignoring the scroll lines number in the mouse control panel.
 
I've had this issue for 6 months or more... a few months ago when I contacted support they didn't understand what I was talking about so I'm glad to see I'm not alone and the issue is now recognized.

The only way I've found to get around this issue of 2x mouse wheel scrolling is to connect the mouse directly to the windows virtual machine instead of allowing it to be 'ported' through the mac. For example while in coherence mode, from the Parallels menu bar icon, select Devices - USB - your mouse... if you're using a USB mouse. Granted, you lose the ability to control your mac with that mouse, but for the odd application where it's critical it provides me a workaround. Meanwhile, I keep a wireless mouse connected to my mac to retain control of the computer. Not a very clean solution but it gets me through.

It does prove however that it's the process of porting the mouse signal through the mac that introduces the double scrolling. Connected directly to the windows VM, the mouse behaves properly and follows the scrolling settings which you set in the windows control panel.
