Internet explorer compatibility issue

When we open freepbx web gui in internet explorer, most of the pages work fine except the ones having select lists. When we open a page having select list and mouse over the labels, all of the select lists are hidden. When we move the mouse away from labels then select lists appear again. Can anyone suggest me some solution for this problem?

I’d consider this a bug. So please post it in the bug tracker (left hand side, under development). Posting it here will only get lost and the person or persons who are responsible for it probably not see it here.
