Sorry, I should definitely have expanded somewhat.
I have recently installed Little Snitch (@ 3-4 weeks ago) on my Mac to alert me to any attempts to instigate contact with the outside world via the net, so I am aware if anything untoward has found its way onto my Mac - I'm not the only user.
When starting up InDesign CS5 this morning, and later with Illustrator CS5, Little Snitch opened a dialogue box at the same time the CS5's application splash screen appeared, informing me that InDesign/Illustrator "wants to connect to tss-geotrust-crl.thawte.com on TCP port 80 (http)".
Merely wondering is this usual or is this suspicious, and why is it doing so? - and why has it only occurred today?

Sure, nearly all of my applications are permitted to automatically check for updates:- even Microsoft's!
It wasn't that:- the IP address ranges for the requested connections appear to belong to Verisign: I know (roughly) who Verisign are, and what they do - and I can't see why all of a sudden, applications should want to contact Verisign when starting up.
I've checked the logs in Console, and this IP range doesn't appear before 29 June this year.
I'm always a little concerned by new, unexpected behaviour or actions, but I do confess to being perhaps just a touch paranoid re ungodly things getting onto my Mac.
