Saved Searches

[luigimilano]

Model Manager 14.50
When I start Model Manager I see Saved Searches (see attach img-1.jpg).
After a period of use Saved Searches disappears (see attach img-2.jpg).
If I try to save a new custom search I obtain an error (see attach img-3.jpg).

Is this an recognize error?
Is there a workaround?

Thanks in Advance
Best Regards
