Multiple Google Accounts and the Market

I have multiple Google accounts like below:

1. Account A (my primary account).


2. Account B


3. Account C

I only have the extra two accounts for gmail (via Google Apps for domains) and don't use them for anything else.

I only want to use Account A on the market. I currently have an annoying issue where the market app keeps using Account B, so I end up downloading things to Account B by mistake.

Is there anyway I can remove these other accounts from the market or set some sort of default account?

Thanks

Update: I know that I can press menu in the market app and select a different account, but this is annoying because it defaults to Account B. My crazy theory is that when looking for updates (in the background), it first checks Account A and then B. Because it checked account B last it leaves that as the active one. Account C has never downloaded an app so it doesn't check for updates.

Answer

This seems to have been fixed in version 3.3.11 and above of the market app.
