I posted this issue on the RB forum and got confirmation from another user that this happens. i'm posting here to reach a wider audience of experts.

if i set ozone 9 elements for the final mix and close the window the sound is fine. but if i reopen the fx window for example to see the eq settings ozone suggested, ozone reverts to 'start again' settings.

from memory i think nectar does the same on vocal tracks. if i save the song the settings seem to stick as far as my ears ca hear but most of the time you have to get everything right before you reopen the fx window or you lose what you had set up. even after saving the interface appears at the start again screen. other plugins open normally with the settings i assigned.

anyone else see this happen? its a pain when you want to tweak another plugin.
