With the Apple Mighty Mouse (still the best mouse they made, despite its flaws), those websites continue to scroll a bit after I've stopped moving the ball (which should stop the scroll dead in its tracks). This is not a mouse or driver problem, it's a misinterpretation of low-level events by badly-designed Javascript. -- Rick Mann rm...@latencyzero.com ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I downloaded MacPass 0.7.3 and created a new document with 200 entries in what I believe to be the MPTableView. I tried scrolling with a Logitech M510 mouse wheel using the standard apple driver (no custom driver installed). I also tried scrolling with track pad on a MacBook Air. Normally a mouse wheel with detents will have acceleration when scrolling but no momentum. Normally trackpad will have momentum when scrolling. This behavior can be seen when scrolling in TextEdit, Contacts, and Mail. When scrolling in MacPass with a mouse wheel the initial delay I believe is due to acceleration which appears to be normal. However when mouse wheel movement has stopped scrolling still persists for a short period of time almost appearing to be momentum. This is not normal. A mouse wheel has no momentum if it has detents. So this is a puzzle. --Richard Charles ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Scrolling differences when using Trackpad or Mouse-Wheel
At this point I am comfortable eliminating the mouse as an issue for you. You are right, mouse wheel processing is different. It came into the system well before the trackpad support. I believe macOS is in the second or third generation of trackpad support, with the last change adding gesture and depth control. Good luck finding the problem!

Re: Scrolling differences when using Trackpad or Mouse-Wheel
Logitech mice don’t have drivers for the Mac these days, but the Options software can add interesting capabilities. It is not required for general use, but is required if you want any of the additional buttons or features to be used. The next question I would ask is how you have the mouse attached to the computer - Unifying receiver or bluetooth (BLE). It does make a difference, we have seen interesting lag issues with BLE that don’t exist with the Unifying receiver. If you are using BLE, I would suggest plugging in a Unifying receiver that is paired to the mouse and trying the mouse with that method of communications. I’m not saying this is a mouse issue, just trying to make sure it isn’t one.

Re: Scrolling differences when using Trackpad or Mouse-Wheel
I'm using a Logitech mouse without any additional drivers installed. I tried using a couple of Logitech mouses, directly attached to the Laptop, attached to the Hub inside the monitor, nothing changes. Every mouse behaves the same way that is, it's lagging on the initial scroll. I'll try to find some more mice from different vendors to see if this makes any difference.

I have mice from a number of vendors (including Apple), and scroll wheel behaviour definitely differs significantly in some cases; also, it can matter whether or not you install the vendor’s software (mice usually work reasonably well without, but installing and running the vendor’s software can change things significantly).
