Apparently (so far), you're the only one.

To which Leonid responded:

I agree with that. Sounds like you might have some files that
were not recompiled from a previous version.
The logic for determining (among other things) whether a page should
be pushed changed in 2.8.3dev.16 -> dev.17:
* new functions for keeping track of temp files (and some other files) for user
interface pages: LYRegisterUIPage(), LYIsUIPage(). ...
If you ant to trace around a bit:
- Make sure mainloop's ForcePush flag is FALSE when the LYpush in question
occurs (i.e., aftter pressing enter on the LYNXPRINT://TO_SCREEN/lines=15
link).
- Make sure the LYwouldPush() called near the top of LYpush() does return
the right result (i.e. FALSE, in this case). This in turn should follow
from LYIsUIPage(docurl, UIP_PRINT_OPTIONS) returning TRUE.
