I have encountered this one from time to time and was wondering if anyone else has (or has a solution).
I am entering bills and select a vendor for whom I have open POs. I select a PO and the line items are shown. However instead of staying open for me to fill in the freight, invoice #, date etc.. it immediately saves and closes. It's as if I pushed the Save & New button (but I did not).
Once this happens once it continue to do so until I reboot QB. It's highly annoying.
