Steen,
Used to live in Palatine/Inverness and went to my 40th at Fremd last year ... so hi from Texas from a former native.
Do agree with Zach - likely a setting somewhere in your software or browser or internet provider. When I blogged on the paint job last fall, I'd leave in mid-sentence to re-play football stuff or make dinner or go to the store - never had a problem with continuing my post.
Wish I could be of more help in solving your particular problem.
