Can you send the schematic file, so I can check it...
Thanks for trying Qucs,

I just copied the schematic into my win32 version right here and connected
both circuits: and it worked with no problem...
Apperently a numeric (machine dependent) thingie. Please try to set
the "Solver" property of transient simulation box to "HouseholderQR"
and let me know...
Hope this works, Stefan.
