I've a situation where I need the action method for an NXBrowser
to modify the values in the browser.  Unfortunately, I've been
having some problems.  [This is under NS2.1.]

An obvious incantation to reload the browser would be to incant
[browser loadColumnZero].  _But_, there's a problem here.  The
action method will have been called from a Matrix in the browser
- and loadColumnZero frees all of the columns and then recreates
them!  So, when you return from the action method after doing a
loadColumnZero, your program crashes (because the Matrix id was
moved out from under the Matrix mouseDown: routine).

OK, another option is to do [browser reloadColumn:0].  This _works_,
but not all that well.  What happens is that I get the output:

Assertion failed: You removed a View from the View hierarchy that
had been lockFocus'ed

which isn't quite what I wanted, either.  The solution that I've
used is to schedule a delayed method invocation via
perform:with:afterDelay:cancelPrevious:.  This works, but does have
other drawbacks.  Anyone have a better idea?

Thanks,
