[otrs] Customer User Change UI issue?

Forgive me if this is a known issue... I've only now spent a significant amount of time on the 3.0 demo site... I found the following UI issue: * In Firefox 3.6, * in the "Change Customer of Ticket" popup window * If the customer user drop-down list is long enough, it is hidden behind the Customer history table header bar You can see below the bottom entry "Michael Testing" appearing from behind the table header: Hopefully this is a simple CSS Z-Index fix? Sorry for the late input... and I should add that 3.0 looks great. Looks like updating and training will be a good 2011 New Years project for me :-)
