Rollup notifications have no action

[dr.nixon]

I keep getting Rollup notifications for things like new mail (using Thunderbird). Given the behavior in Growl I expect that clicking the notice would take me to the message. It doesn't do anything. I noticed a forum post earlier that said double-clicking would fire the action - it doesn't. No method of clicking seems to work, using any of the common modifier keys. This seems strange; why show me the notifications if I can't do anything with them? At least collapse them (so that it says something like "X new mail messages" instead of a notice for each one)...

If clicking doesn't do anything at all, could we at least have clicking on the window close the notice? As it is I have to target the little X in the corner to close the Rollup window. Being able to click anywhere to close it would be better.
