Windows 7: New Windows 7 PDF troubles

Can anyone tell me what I need to do so that PDF files I open, mainly from the web, will open full screen roght away...? What happens now is that the file seems to load ok, but it does not dispaly "full screen" and a 'Adobe' icon appears in the task bar. I click on the icon and the PDF opens full screen.

If I open a PDF from one of my local files, it opens "full screen" right away, no icon thingie at bottm of task bar...?!?

Cheers

There was another thread just like this (I'm not sure if that thread was eventually solved though).

I've got no idea how to find it though, as the site search is useless.
You might have to try asking one of the Admins/Mods "to point you in the right direction".
