Toni, this is what I've got by way of configs on WinUAE at the moment:

"Foebane" is my main Host configuration, which I've adjusted for display, sound and filter, and "FoebaneWB" refers to the HDD paths I've specified for the Workbench install on C:\Workbench. I found out later that at the moment, it's also set for A4000/040 because I set the quickstart system to that before I added the HDD paths.
