verify the path to the partials is in you files paths settings if they are not in the default folder location
This appears to be one of two keys...
Key 1: Workspace Settings >>Save Changes to workspace
Key 2: Add paths to cui files to files path
NOW CUILOAD the partial CUIs.
Load will now be permanent.
Seems odd to me, but:
it appears that once you have defined the workspace as above, you can create a new workspace which does not include the pathing for the partial CUIs, but if they are (permanently) loaded when the workspace is created, they will come along for the ride.
@ dgorsman:
I encountered this in 2011 also, but forgot what I had to do to fix it.
Thanks, folks.
