accounts self closing in the ledger

[Jack]

I have been noticing this on occasion for some time, and still can't  
quite put any pattern on when it happens.

When I reconcile my investment accounts, I start by opening both the  
investment and brokerage accounts in the ledger.  I then clear  
transactions in the investment account, and then do so in the brokerage  
account.  When the brokerage account matches the statement, I reconcile  
it.  I then switch to the investment account, and then to the  
Investments View, where I confirm the number of shares for all  
securities in that account.  At that point, when I switch back to the  
Ledger View, about half the time, the Investment Account is no longer  
present, and I am in the Brokerage Account.  I often don't even notice  
until I start the reconciliation, and note that the date is wrong.

I don't know if anyone else has seen this and felt (like me) that it  
was just too odd and uncommon to bother reporting, or if it's just me.   
Does anyone have any suggestions on what I might try to track down any  
possible cause?  Would it make any sense to run under gdb with an  
interrupt place on the ledger code which would close the account?
