Merchants: Purchasing Stacks Boots Me from Merchant Window

[tobolamr]

So I have noticed an intermittent bug, and it crops up all over from time to time. On attempt to purchase a full stack of anything, about 10% of the time I hit "buy" and it just closes without performing the transaction. I can go right back in and buy it without fail afterwards. Not sure if it's a game bug or if it's a client side bug. Can't find any corroborating info on what might be triggering it, either.
