Yes, that's what I'd have recommended. But I'd say there was (and maybe is) a 
bug in there somewhere because the model compilation adapter should normally 
strip away training data for untrained words before starting the compilation 
to avoid this issue.

But compiling the model with the full lexicon is of course the recommended 
way. Just make sure it still works if you add a word and don't train it 
(independent of the scenario- / acoustic model switching).

Great! Can't wait to try this out :D

This is weird but it's not a common problem. Could it be that restoring a 
model from the cache doesn't lock the temporary path or something like that?

If the synchronization does not complete it normally means that 
SynchronisationManager::commit() fails...

As this now in the configuration screen of simon, you get the save() and load() 
calls from KCModule.
I'd load the config once on program start (and just retrieve the already loaded 
config in load()) and save (and apply) it whenever save() is called.

Also, make sure that the Cancel button works -> don't work on the real 
configuration but a copy!

Btw.: There seems to be a very annoying bug somewhere in the caching system. 
If you start with a fresh installation, simon will complain about not finding 
something in the cache. Could you please have a look?

Best regards,
Peter
