>Description:
we noticed a small bug in Insight's memory window: when the
display format is changed, (from "Word" to "Byte", for example), the address displayed resets back to the default (which is usually the start of the .data section).

I looked at the code in memwin.itb, and the reason seems obvious: the member variable MemWin::addr_exp is never updated (after being initialized to .data). MemWin::reconfig, which is called after a format change, uses this value, and therefore resets the address to the default.
>How-To-Repeat:

>Fix:
A simple one-line change fixes this; I include a small patch below.
BTW: this was Insight from gdb-6.1, but memwin.itb apparently hasn't changed since then.
