I love MicroB and use it most of the time BUT on some vBullletin forums (Version 4.0 or above) the 'edit' 'reply' report post' buttons are all overlapping each other. As I run my-own vB4.0 forum I need to be able to edit, merge,move posts at a moments notice MicroB cant help me if I'm on the move....

Firefox is slower yes but does not have this glitch and allows full editing of all vB 4.0 sites. it's good to have a choice!
