in my auto-generated two column index (registry) there are several cases of widows - it is the last item of the given letter which overflows to next column/page:

--------------- (start page) ------- Usti 29 (! alone !)

V Vamberk 18 ... ...

There are also few cases of orphans, but this is not so strange: ... ... Josef 29

K Karel 69 (! alone !) ---------------- (end page) ---------

In my setup I have defined (with no luck):

\startsetups[grid][mypenalties] \setdefaultpenalties \setpenalties\widowpenalties{2}{10000} \setpenalties\clubpenalties {2}{10000} \stopsetups

\setuplayout[grid=yes, setups=mypenalties]

After finishing another duties I am back ... and still facing these issues. I think both cases could be eliminated by establishing a new constraint to the 'key letter': (1) There must be 0 or at least 3 lines at the beginning of the page/column before the Key letter. (2) There must be at least 2 lines after the Key letter. Can this be somehow set in my source file? Thanks, Jan
