Wmode is a very buggy area, with multiple issues in multiple browsers,
and I think that Adobe itself could qualify best if they themselves or
a browser vendor should solve an issue, so I would say, in any case
report it to Adobe, and I hope they will address it soon, because,
because IMO the wmode topic as a whole is kind of a troublesome area.
A short while ago I made a list to capture the different issues around
wmode:
++++
Issues reported on the SWFObject forum:
Firefox 2 / XP SP3
- flash including mouseover/button
- wmode = transparent
- scroll down HTML page until Flash is outside viewport, scroll back
up:
- SWF now requires click-to-activate
Opera 9.50 / XP SP2
- wmode = opaque
- SWFs with do not appear and if you try to right click, you will get
"movie not loaded"
message. After F5 is hit, movie is shown suddenly.
Firefox 3 / PC (NOTE: this is clearly a FF3/PC issue)
- does work correct in in FF2/PC and FF3/Mac
- using object element
- flash including mouseover/button
- using wmode transparent/opaque
- Firefox 3 on Windows has a different default style for the object
element than in Firefox 2 or for the equivalent embed element, so it
treats it like an active link.

SWFObject static publishing authoring issue (NOTE: an often made
authoring mistake)
- When using static publishing ensure to define your wmode parameters
for each object element
Reported workaround to the problem with having to click to get mouse
events to work in FF is on scroll have a container div change it bg
color:

All these issues listed here are very common issues web developers
face every day. None of these are caused by SWFObject.
