Many (not all) Quick Links don't seem to work properly or consistently for me. For example, if I click on Mark Forums Read, nothing happens. If I click on it again, it might work. If I right click on it and select 'Open in New Tab' or 'Open in New Window', it works fine.
A fairly minor annoyance. But since I use the Mark Forums Read command often, it is...well...annoying.
Anybody else?
