I am experiencing extremely slow (30-60 seconds!) opening of Office
Documents and web pages when a document, or a link, resp. gets
double-clicked. The delay is not present if an office app is started and
the document is then opened from within (or by dragging the document
into the application). Same with IE: if I start it and drag or paste the
URL into the address field, it is openend "immediately".

After some longish searching I found out that I can fix this by changing
the file associations (or URL-HTTP association) from using DDE to not
using DDE. But I would rather fix the obviously underlying problem with
DDE itself!

Any ideas/suggestions what to check, enable or fix to resolve this
issue?
