Outlook Web App in Safari v5.0.6 (5533.22.3)

Hey guys, quick question,

I am using Safari v5.0.6 (5533.22.3) on my Mac OS X Leopard (10.5.8) and have trouble attaching my attachments to our corporate webmail. Exchnage 2010 SP2 supports Safari 3.0 and higher it seems.

When I click on the paperclip icon to add attachments, nothing happens.

Does anyone know what the fix to this may be?

Thanks in advance.

Chris
