new hint on account unmapping problem

[Jack]

Since the release of 5.0, there have been several different threads  
about accounts not being able to update (direct-ofx) but still  
appearing mapped (you can unmap the account, but not update it.)

I just ran into this again with a version compiled from git head maybe  
two weeks ago.  (I'm starting a new compile now.)  My main investment  
account showed this problem.  So - I unmapped and remapped, set the  
download start date, updated the account, fixed some transaction  
details, and saved the file.  I noticed some apparently missing  
transactions, and went to update the account again - but it was back in  
the starting state - no online details in the account edit page, but I  
can unmap and remap.  I did that, then immediately saved the file, and  
it reverted to not being able to update the account.

Does this seem like something in the file/save process is changing  
something so it won't work?  I have not yet identified anything in the  
file that seems wrong, but other accounts at the same broker (Merrill  
Lynch) continue to work fine, so far only this one account shows this  
problem.

Does this trigger any thoughts as to what might be going on?
