 There seems to be more than one reason for staining in the Se.  If there 
 is a lot of dissolved silver in the final fixer - and thus dissolved silver 
 in the print - there will be staining.  The second fixer bath has to 
 be really fresh.

You're right, my usual procedure is to wash the prints for 5 minutes in running 
water (while I'm exposing and processing the next sheet) and let them stay in a 
sink until the end of the session where I tone them all one after the other.

With the same F-9-like fixer that looks bad to the iodide test, I tried to:

- put the print directly from the fixer to the selenium -> staining

- put the print from the fixer to a short (10 seconds) rinse to selenium -> 
much less staining but still some

- wash the print for 5 minutes between the fix and toner -> no staining

I've the impression that Ishould be able to tone the print after a shorter wash 
than 5 minutes but was a bit short of time to test it this week-end.

The idea being to put the wash and toning in-line with the previous steps and 
letting only the final wash to be done at the end of the session.
