Status: VERIFIED DUPLICATE of bug 180078

(SeaMonkey :: Sidebar, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2.1) Gecko/20021130
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2.1) Gecko/20021130

The up/down sidebar scrollers near the bottom of the sidebar window either:

A) Incorrectly respond to middle and right mouse clicks.
...or...
B) Are painted incorrectly when the middle and right mouse buttons are clicked
on them.

Under Windows, I (and Microsoft ;-) prefer option (A).  In other words, neither
scroller button (up or down) should respond with a tab scroll when clicked upon
by the middle or right mouse buttons.

If such functionality were permitted with Windows GUI standards, then option (B)
would apply.  In other words, the scroller buttons do not depress (read: get
painted properly) when they are clicked with either the middle or right mouse
buttons -- yet they still perform their scrolling functions.

Reproducible: Always

Steps to Reproduce:
1. Press [F9] to toggle the Sidebar window ON.
2. With more than a half dozen tabs active, you should see the sidebar scroller
buttons visible near the bottom of the sidebar window.  If so, then continue. 
Otherwise, enable or add more sidebar panels until the scroller buttons are visible.
3. Right-click on either or both scroller buttons (up and/or down).

NOTE: You should have witnessed a scrolling action.  This is incorrect under
Windows.  Likewise, the buttons were never "depressed" to visually indicate that
they were being pressed.

4. Next, if you have middle mouse button (or a mouse scroll wheel that supports
clicking), click it.

NOTE: Again, you should have witnessed a scrolling action.  Like above, this is
incorrect.
Actual Results:  
Scrolling occurred, and it shouldn't have.  Also, the buttons were never painted
in a "depressed" state to visually indicate that they were being pressed.

Expected Results:  
If no pop-up, context-sensitive menu was assigned to these scrollers, then
Mozilla should have ignored both the middle and right mouse clicks.  Otherwise,
it should have displayed the pop-up menu.

I am using the Gray Modern theme, with both mouse gestures and autoscrolling
projects installed.
