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.
