new version 1.0.4 has been released that fixes this z-index bug
Updated to this version and clicking review link on product page or reviews page does nothing now. Backoffice configuration works.
Is updating merely unzipping and replacing with the new module folder, the old version folder?
Edit: reverted to the earlier version and it works correctly.
Edit2: thanks @datakick for assisting on this, apparently I was using the source from github and not the module fro the store itself
