Trouble saving with built-in particle editor

Hi,

i'm having a problem when saving changes i do with tge's built-in particle editor (F5).
When i select an emitter (for example) i edit it and click on save - everything works fine till here. The next time i start torque and check the effect - i only get the old effect with out my changes.
My changes simply seem to not have been saved.

Thanks for any help :-)
