Thanks for the fast answer :) I am running PSPad as administrator. The installation was also done with admin privileges.
File types are correctly associated - I double checked. PSPad icon used for file associations is showing in explorer. If you point me to the registry settings I can check there. -- <http://forum.pspad.com/read.php?4,50992,51005> PSPad freeware editor http://www.pspad.com
