Can you try running OSPF over your Bri0/0 interface so that the watched route will be learned via that interface and see what reaction you get to the idle-timeout expiring again? An easy way to do this is to "no passive-interface bri0/0" in the OSPF process and either run an OSPF demand circuit, or (my preference), simply declare OSPF hellos and updates as uninteresting traffic.
Let me know...

Subject: RE: Dialer Watch with Dialer Maps. Why does it only work with classful watched nets
Here is the output from the debug. What's really interesting is that just
now, it worked fine when I first configured the Dialer Watch. The ISDN
came up, and passed traffic when it noticed that the route disappeared from
the route table. When the IDLE time timed out, the ISDN went down, and
would not come back up unless I toggled the watched interface. After
rebooting both routers at either end of the ISDN line, it now no longer
works.
