For some reason, Cmd/Ctrl+Left Click works different in Aha! than on other sites. Everywhere else, it does the same thing as middle-click or right-click | Open Link in New Tab.. it opens the resource I'm clicking on in a new browser tab.
For some reason, Aha! seems to trap this event and just treats it like a normal click. I don't get the new tab I asked for, I just get a fly-out dialog thing. This isn't the end of the world, it's just annoying to bump into all the time when I'm switching back and forth other web sites/apps and Aha!.
