So if I understand you right, the correct way in WE 7.1+ to have one
method of a class register a timer callback to another method in the
same class called cb1 would be
schHandle = startTimer(1000, "me.cb1")
That would indeed save me some inconvenient delegate functions. I've
had funny luck with "me" references before but never finished figuring
out why.

Well, then, prepare to be proven wrong. In Window-Eyes 7.1 and later,
you can pass a string like "MyObjectInstance.MyMethod" as the callback
to functions that let you pass a function name as a string. That
includes StartTimer, Queue, ConnectEvent, Dialog, Menu, and some others.
Obviously, this only works with ActiveScript clients. If you want to do
it with .net clients, you'll have to use a delegate. For C++ and VB 6
clients, you're on your own; you'll have to simulate delegate
functionality somehow. (That probably means creating a shim object that
exposes an IDispatch interface to WE and passes any calls on that
interface on to the object method you wanted to delegate them to.)
