Hello Thorsten !
Thanks again. You wrote

I am glad to hear that ! SMILE !!!!
Yes, I have re-installed the operating system (in fact, I have done that several times).
Yes, there is a network installed. Nothing special, and in idle-mode (before I start WDP) the CPU-usage is 0-1%.
Here is a repeat of all I have done so far (as far as I can remember):
I re-installed (again..) Windows XP Professional. Absolutely NO other software, no extra drivers, no virus-scanner etc has been installed. CPU-usage before WDP is 0-1% (se my messages in the forum).
I re-installed (again..) WDP, and upgraded to the latest version (english) found on the WDP-homepage. I checked all the setups to the best of my knowledge, but find nothing wrong.
I uploaded new software to the Intellibox. I thought I had the newest, but today I found one newer, so I updated it today.
I made a new RS-232 cable, making sure that it is correctly wired.
I tried with 2 other computers. First with one similar to my own (500MHz and 384Mb memory) but with Windows98SE instead of WinXP, as I normally use. No change. Next I tried with my sons "racer", a 2.6GHz PC. Same result, only difference was that the loco did stop a bit faster after the "overshoot".
From before I have exchanged the Intellibox for a new one.
I have installed a new RS-232 card in the PC.
I tested with running only 1 loco through the entire layout. No problems at all, loco always stopped correctly. As I ran only one loco, there were no other routes to switch...
I tried with 2, 3, 4 and 5 trainsets. Everything does work perfect as long as no routes are being switched as one loco is just about to enter the brake-contact. But every time one route is starting to switch just as one loco enter the brake-contact, that loco always "overshootes". It does stop, but too late.
I run only Demand Contact (which I love, by the way !).
Regards,
Per.
