LadyCFII posted about the "r" key for store restocking in
this sticky thread, and it specifically states that it only works in versions 1.00.04 and 1.00.05.
Angela -- Before you buy the game again, you might wish to contact Gamehouse and ask them when they plan to release the .05 update for their customers. We sent out the .05 version to all of the game distributors as stated in Arthur's post
here.
