Launchbox freezes when trying to edit Developer field

[Former user]

Using latest version, 7.5 beta 4 of Launchbox. When editing a rom, Clicking on the Developer box will freeze Launchbox. It does not matter if this box is empty or populated. Clicking the expand arrow does nothing. Clicking inside the box freezes Launchbox. This is the first time I have been trying to edit this field, so I am not sure if this is a new bug or not.

It's not frozen, it's just taking a while to populate. That said, this isn't ideal and we do need a better solution for the multi-check dropdowns.
