Yes, maybe we should introduce this additional pop up dialog similar to 
the stock/currency accounts, to ask the user what should be changed: 
e.g. "What part of this txn should be recalculated:
o Amount in this account (edited),
o Exchange rate,
o Amount in the other account,
o Leave transaction unbalanced".

 From what Jan Nielsen wrote in his message, I think he also prefers an 
exchange rate dialog where the amount can be changed too. However, since 
you said this is really a PITA to implement, we should give it a try 
with the additional pop up dialog. Maybe this is already enough to cover 
all use cases.

I'm not confused/over-expecting by the way it looks. I was expecting the 
described "change both from-amount and to-amount in one dialog" 
behaviour, regardless of how the current dialog looks. Now since you say 
this is way too difficult to be done, well, I guess we might get along 
without (but with the additional pop up dialog mentioned above). I 
really know nothing about the internals of the register, so I guess I 
trust you on the PitA question. :)

Thanks. We're not in a hurry right now, so I don't mind whether it's in 
1.7.7 or only later in CVS. I guess I'll continue to use it for my 
everyday data, and I'll let you know whether this works fine.
