Comment 15 for bug 50839

This but is a sort-of follow-up to bug 386687.

Since bug 386687 has been closed because most scenarios have been fixed on the Mozilla trunk with Flash Player versions newer than 9.0.64, I am opening this bug since there are clearly some pages where this symptom persits, probably due to another hidden bug.

The problem is demonstrated on the following page:

http://www.ikea.com/pl/pl/ - when mouse hovers over the large flash banner,
mouse wheel doesn't scroll (but keyboard arrows DO scroll).

While it's not present on most other pages, e.g.:

http://www.arkadia.com.pl/ - mouse wheel scrolling works fine.

It's hard to tell what causes the problem on the IKEA page, while the Arkadia
page works fine. They both use JavaScript for creating the SWF object, although
in a slightly different way.

An isolated, minimal testcase would be welcome if anybody could come up with one.
