Acrobat Reader doesn't recognise default browser

[Salem]

Hello all,

I'm reading a PDF document containing HTTP weblinks to various world wide web sites.
The PDF in question is this one

Whenever I click on one of these links, it always starts Internet Explorer rather than my default browser (currently Mozilla Firefox).

I've tried most permutations of:
Reader 4.0, Reader 5.0.5 as PDF reader
Opera 7.0 and Mozilla Firefox 0.9 as default browser

So, is there anything which can be done to make Acrobat Reader honour the default browser selection?


Clicking URL's in these applications does the "right thing" of launching the URL in the default browser.
- Thunderbird
- Outlook Express
- OpenOffice

This is on XP with SP2.

Thanks,
