I am losing the ability to use the right click functionality of my mouse within LR.
Of note - Windows 7 64bit - on the rest of my computer i have no such issues (anywhere). - it seems to happen after i have had the program open for extended periods +30-40min. - only seems to have started with 3.4 (for me at least) - re-staring Lr solves the issue for another 40 min
