I sold off an investement and am trying to "sell" it down
to zero quantity and am getting the following error:

"The changes you are making will cause the share balance
for 'LargeCap' to become negative at some point. Please
arrange your transactions to avoid this."

There are 1180.375 shares. It lets me sell 1099.00 but no
more?! There are 81.375 left and I can't get rid of that
quantity. I tried to remove the quantity by changing the
balance directly but it will not record when I click Save
and Exit.

Any suggestions?
