#67 0.0.63 Assign amount wrong preset

[cybrarian]

Assign part of window FMain: Wrong value is preset in amount in certain circumstances:
After changing the amount in an invoice and removing the assignments (ixc records) involved (via phpMyAdmin - interface in facs doesn't allow it yet), the amount presented at selecting the invoice, is still the former invoice/assignment amount.
I don't even understand where it comes from; the records are changed, the lists reloaded.
After exiting the program, the value is reset.
