Realplayer can't run scriptsl blocks webinars

With Realplayer 11 installed on openSuse 11.3, when I join a webinar at the audio buffers but stops after a fraction of a second. If I run the “test your system” at, in either Firefox 3.6.13 or SeaMonkey 2.0.11, the bubbles sample plays both audio and video but there is an error message
WARNING: Your media player does not allow scripting. Scripting is required for streaming events to perform properly. Please re-install your media player to correct your configuration.
Reinstalling does not change the behavior. Is there a way to give an application the permissions neede to run scripts?
