Problems with Flash in AEM Forms Workspace Queue Share Request
In AEM Forms Workspace, when User A requests access to the queue of User B, User B gets an email notification with "Share Queue Request" in the subject line. Clicking the link opens AEM Forms Workspace with a new item in the TO DO list of User B. That item is associated with some sort of Flash interface that isn't loading. Right clicking on it shows "movie not loaded". I'm trying this in IE as well as Firefox. Neither works. I've also tried different settings on IE compatibility view with no luck.

Flash is also used in AdminUI for managing queue sharing (home -> services -> forms workflow -> shared queue uses a Flash interface). This is working fine for me.

So, I know that Flash is correctly installed and runs in my browser.
Has anyone else seen this problem? Any suggestions for troubleshooting? Thanks.
