mouse no longer selects from drop down boxes

[Philip Gascoyne]

Moving the mouse or using scroll-wheel closes the drop down box rather than changing the highlighted option. Problem is not evident on opening firefox but happens frequently and may or may not stop happening during the session.

Possibly dupe of Bug #785195 and still the case on Oneiric. Bug #858745
