Can access stash outside of town. [screenshot] [reproducable]

hey i noticed this bug on accident trading today.

When in Act 1 and trading with that woman (cant remember name) you can see and click your stash, which will open up the stash. While the stash is opened this way, if you click, "buy items" on the same lady, then close the buy dialog, the stash will be permanently opened, even if you leave town.

I took a few screen shots here:
