Gox trade orders not exeucting?

[marvinmartian]

Last 30 minutes:

Log into gox
Check market data (depth)
Note bid prices
Enter Sell order 0.01 below bid price
... wait 10 minutes ...
nothing (bid and ask unchanged in market data)

Check market data again
Enter Sell order exactly at bid price
... wait 10 minutes ...
nothing (bid and ask unchanged in market data)

I continue to switch between the above two, no change.  My orders aren't getting executed even though they are clearly in my queue.
