------- Additional comments from [EMAIL PROTECTED] Mon Oct 1 06:19:02 +0000 2007 ------- This bug affects Intellipoint 6.x aand some MS mice natively (no Intellipoint installed) The issue is how OO handles the delta values being sent in WM_MOUSEWHEEL. MS initially dictated a value of +/- 120 per wheel detent, to allow for future higher-resolution wheels. As it happened, Microsoft developed the free-spinning "tiltwheel" which produces delta values proportional to the rotation speed. -Slowly rotating the wheel will produce frequent messages with low delta values. -Quickly spinning the wheel will produce higher delta values, but possibly less messages. Applications are supposed either use the variable delta to determine how to scroll or accumulate delta until +/- 120 is reached (equivalent to one detent of a traditional wheel) This is documented here: http://msdn2.microsoft.com/en-us/library/ms645617.aspx As far as I can tell, OO is ignoring (and not accumulating) deltas < +/- 120 The issue with Intellipoint arises when it installs the HID filter driver (point32k.sys). Natively, most mice (even tiltwheel) report a fixed delta +/- 120 per wheel event. After the filter is installed, variable deltas are generated by tiltwheels and cause problems with OO (and some other apps, such as iTunes...) Some mice (MS Wireless Laser 6000 for example) natively report variable deltas and will have problems even if Intellipoint is not installed. There is no workaround in this case. for these mice. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
