Do you have an option named "smooth scrolling" (or something similar) enabled in the settings of your mouse?
Please, see if bug 1139302 is the same issue.

Yes, it appears to be a very similar issue. Is there a more perminant fix for this issue yet or one in the pipeline?

FYI - The options for auto scrolling and smooth scrolling in the Thunderbird Advanced Options made no difference.

No, as far as I know.

According to bug 1139302 the "Smooth Scrolling" option is a setting in the mouse's drivers under the OS and not a Thunderbird's option.

Can you confirm that you have a "Smooth Scrolling" option enabled for your mouse, like bug 1139302 ? Please search in the settings of your OS.

I can't reproduce the issue and I don't know how to do it because in the standard drivers for the mouse on Win7 there isn't that particular setting.

Lightning's code related to the issue should be this (for the month view):
http://mxr.mozilla.org/comm-central/source/calendar/base/content/calendar-month-view.xml#1112
and the only thing I can image is that with that option enabled a lot of events of type "wheel" occur with only one notch on the mouse wheel. Anyway it needs to reproduce the bug to investigate.

I did reply earlier(Feb 23). I do have smooth scrolling and when disabled, as per Decathlon's bug link ( bug 1139302) the issue was resolved. However, the question remains - Is there a perminent fix for this issue? - Decathlons replied .. No, as far as I know.
