I don't know if this has already been discussed but I may have missed it.  I've upgrade to the most recent SPLAT a few weeks ago but haven't used Sonar since then.  When I opened an old project all the screen settings seemed to have been reset to default settings (i.e. no console or track icons, wide channel strips, etc).   After changing the settings (i.e. narrow channel strips, small icons, etc) I saved the project.   When reopening the project I see the settings as saved for about 1 sec then the project reverts back to all defaults settings.  
 
Is this a bug in the latest update where the screen settings don't persist or is there something new I missed.  

If you have Lens' enabled, try setting it to "None".
Also try locking your screensets when you have a view you want to keep.

Chuck,
Thank you.  That was exactly it.  Lens was enabled but I hadn't read up on it yet.  Thanks for your quick assistance.
