Hi Guys,
See the attached. Does anyone know why the filter button is greyed out in real-time log viewer in ASDM?

I'm using ASA version 8.2(2)59 and ASDM version 6.2(1). I have full access to it with Level 15 privileges. I don't know why this is happening, it's preventing me from building a filter. I've not seen this before. I've tried to workaround by manually typing in the filter string ie: FILTER:srcip=192.168.0.1 for example but it still won't filter anything! A setting someone has enabled on this box maybe?
