I have this big lag on right click, running the 0.43.4 version for MAC OSX.
I've found one report about this quite annoying bug, which did not give me any hope (basically we have to wait for the next stable release?)
Frankly it makes this version pretty much unusable for me so I'm trying to install the previous version (0.42.5) but I have troubles too. With the .dmg binary some libs are not loaded ("can't load ... " etc) I don't know why. And I'm unable to get the all platform sources to compile (started a thread on stackoverflow : http://stackoverflow.com/questions/25083741/trying-to-compile-sources-on-mac-os-x ).
I have an old 0.40.2 that works fine but I would really like to have something more up to date to work with.
This lag bug on 43.4 is really a wiked one, has anyone experienced it? A corrective patch would be awesome.
