I created a simple plugin to upload photos to meetup.com from lightroom. Since LR5, some users have complained that everything works for authentication, but when they try to select an option from a simple_list, the option appears unclickable.
It works great on my OS X install of lightroom 5. The people that complain seem to have Windows 7 64bit in common, although I'm not certain that's the cause or just a coincidence. Has anyone had this issue, and if so, any suggestions for repair?
