Object reference not set to an instance of an object.

[YYZ]

I get this error in my Task List periodically when going into design
mode for a usercontrol -- it is annoying because I see .Net freeze for
about 10 seconds, then eventually is slides up the Task List window
with this error -- I know it is coming, and I can't do anything to stop
it.

The error doesn't actually hurt anything -- project still compiles and
runs fine with it sitting in there happily erroring away. However, I
want it to stop.

Can anyone give me some pointers on what might be causing this problem?
It is on a usercontrol that is hosting a couple of other usercontrols
and some native controls at design time. Well, at runtime, too, but
you know what I mean.

Any advice/pointers/articles would be greatly appreciated.

Can't you set your debugger to break on all exceptions and find the line that
is causing the problem?

I honestly can't find that -- where do you set that? I searched the
help and didn't find it, and it wasn't in options, and I couldn't find
it in the menu items, either -- what am I missing?

In VS2003 it is under Debug->Exceptions
