It's only about the loading, and actually I was wrong, as it's only a problem of
launching time -- just see this commentated "screenshot" :

I got the same situation with fftease. I first thought they didn't work because
of the watchdog messages, but actually you just have to wait and the normal
situation gets back after, say 10 seconds. 

I use the PlanetCCRMA/RH9.0 distribution of Linux (with the PlanetCCRMA
low-latency kernel), the sound card is a RME Hammerfall Multiface.

I hope this will help. If you need some more information, please ask me

Sorry but I didn't have the time to test your objects inside patches, if there's
a later problem in use I will tell you.
