FYI, the trigger for this bug is using copy/paste in the batch transaction screen.  I hate this bug too, especially because it's when you're posting large amounts of transactions like to post a year's worth for tax time, and that's when you really need to copy/paste AND have recall on transactions working.  It's a flaw in every desktop version since they added batch transactions and none of their 'fixes' work.  The code is screwy somewhere and no one in tech support is willing to try to actually fix the program.
