This is a known bug (at least, it's known to Macromedia/Adobe). The
Linux version of Flash does not allow transparency. I remember this
being mentioned back when Flash Linux was still in beta (the beta
creators blamed it on Linux version Firefox, if I'm not mistaken).
There's no known universal workaround (from user-land). In most cases,
you can click on the top level of the menu and the next page should show
you a drilldown of choices. Other times, you'll have to disable Flash or
adblock it.
On citicards.com, there are several layers of Flash overlaying each
other. The only way to log in is to block the top one. My Adblock Plus
rule for this is:
*citicards.com/cards/wv/swf/filter1.swf
As web developer, there's an ugly workaround:

Hope this helps.
