Since upgrading to 11.04, when I use WebEx in either Chrome OR Firefox, and select "Share Application" I can click on applications running on my desktop, but they aren't shared. No errors are displayed. This worked fine before I upgraded. I can "Share Desktop" okay, but I'd rather have "Share Application" working.
Possibly related: Pandora loads maybe 60%, then stalls out. (But we're talking Java vs Flash, I think ...)
