Since I updated to 6, my mouse wheel scrolling has become erratic, and, depending of the text size on the web page, either moves only a few lines each turn or moves several pages instead of one page as it did before on every tab. how do I fix this?

Question

Is this a glitch or is it something to do with compatibilty?

Answer 1

yes, it is still happening, though I've gotten better at ignoring it.
my touchpad, i think, is an elan ps/2 port smartpad and my mouse is a microsoft basic optical mouse v2, both componants are working correctly and have the latest driver update installed.
The difference between img 1 and 2 is one scroll wheel turn down. In image 3 I have decreased the view using control - (minus) and in image 4 I have scrolled down one turn of the wheel. you can see that instead of a full page turn, like between img1 and 2, it only moves about 2/3's of the screen down. As every tab seems to have a different text size, the amount of scroll turn changes between tabs, sometimes varying as much as several pages each scroll turn.
One thing I have noticed, is that the vertical scrolling speed on my mouse settings changes the amount the pages moves when turning the wheel. This only seems to change when in firefox. changing this while using word has no effect on the page movement in word. Increasing the vertical scrolling speed will make the scroll turn move further.
I have adjusted the scroll settings in options, and no adjustment of settings, (autoscrolling on/off, smooth scrolling on/off in and combinations of off/on) has made this error stop occurring. I have checked for malware etc, no issues. This happened from the instant I upgraded to FF6, so I think there is a corrolation there.
