When submitting a new bug thru bugzilla, the component selection scroll window
is annoyingly short, such that scrolling down to the appropriate package name is
a real pain.  The area above and below the actual scrollbar is little more than
a few pixels high, and you have to be extremely careful to place the cursor if
you want to use that to scroll at an even moderately acceptable speed.

  Can that be made a bit taller?  Or, even better, can there be a text window to
accept the package name directly?  Or at least a prefix?  Anything would
represent an improvement on the scroll window that is currently there.
