Modifying a Corridor Section

[Anonymous]

I have a corridor that daylights using the Multi
intercept thingy.  I've set it to 1 so it daylights to the first
intersept.  All of my sections daylight properly to the first
intercept.  There is one section, however, that I need to change to 2, so I
view corridor sections, find the offending section, and click the down arrows so
I can modify the parameters of that section.  As soon as I click the "1" to
change it to "2", the whole thing goes crazy.  Starts flashing and
blinking, but never actually let's me change the number.  I've seen a post
on something like this, but I thought I'd reiterate.  Does someone have a
solution yet?
