This was observed with both a RadeonHD 7750 and Intel HD4600; both using stock opensource drivers/mesa et al. Two separate machines, btw. I'm afraid I sold my nVidia card that I used to use, but the fact those can't drive more than 2 monitors at once means I wouldn't have chosen the configuration that revealed it in the first place (ie: wanting launcher only on middle of three monitors). I suppose it's possible that nVidia's TwinView may be having an effect, if it means the logic of how it handles multi-monitor is reflected up at the levels at which Launcher is coded. (In that case Nouveau might show it.) But remember from earlier observations: this only occurs if the launcher is placed on one screen, not all of them, and that the screen it's placed on is *not* the one on the left.
Is clearly a bug :-) Can't possibly be a design feature a: that the launcher behaves differently on different monitors of a multi-monitor setup, and b: that it works correctly exactly once per session. *Never* working would at least imply malign design choice! ;-) Also, it didn't happen in Saucy. I'd had that Launcher-in-the-middle config for some time before the upgrade to Trusty beta. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

Status in “unity” package in Ubuntu: Triaged Bug description: In Trusty: On a dual monitor system with the launcher on the right hand screen, an application that has been "locked to launcher", (including those there by default) can only be clicked on once per session to actually launch the application. After that it's unresponsive to clicks, although right-click actions work. Seems to affect all apps, including "Files". To repeat, for any application not already on the launcher bar: Launch the application using the dash. Right-click on its launcher icon and select "Lock to Launcher" Quit the application. Click on its launcher icon. It should launch again. Quit it again. Click on its launcher icon again. It won't work this time. It looks like dragging would work, but its operation as a launcher will not. NB: I haven't installed any hacks eg: click-to-minimise. Seen this on two systems upgraded from saucy to trusty. (One with AMD graphics, one with Intel, so I doubt that's relevant either.)
