Strange?

Last week I was reading of another forum member's woes of coolant leaking everywhere. Then another member stated that it may be his coolant cap and that there were updated caps available with part # ending in .02, .03 etc. I was thinking I should check mine. Sure enough mine had a pn# ending in .00. This was last Wed. or Thurs. Anyway... I decided it was cheap preventative maintenance and I hadn't spent any $ on the Boxster lately so I ordered an updated cap from suncoast. It should be here today. Ok, for the unbelievable part. I drove the car last night for the first time in approx. 3 weeks. When I came to a stop in my driveway it leaked coolant in front of the RR tire all over the driveway. I immediately opened the rear trunk and sure enough I had coolant around the cap in the service tray. Crap! I'm sure this is the culprit as it is not leaking anywhere else but there. So I'm thinking how weird that I ordered a part for something that hadn't even failed yet. So give me some logical explanation here guys... Did I disrupt something by removing the cap to look at it last week? Is it just a coincidence? It's a '00 S with 38k mi. So a lot of garage-queen time. I checked/removed the cap last week when the engine was completely cold and had been sitting for 2 weeks so no harm in altering pressure in the system or anything. I think the cap probably hadn't been "disturbed" in years. Also, I took the trim piece out of the service tray to reveal the other relief valve etc. I wanted to know where the coolant all went. Is that a tiny drain hole in there? I just wanted to make sure coolant didn't go somewhere undesirable in the trunk or cabin. So thank-you to whomever had the coolant cap problem last week. You prompted me to order an updated one and to fix a problem I hadn't even had yet!
