I recently came across a strange bug with split transactions and the
auto-single line display in GnuCash 1.3.7. A vendor billed my account
in two separate transactions for a single order. Since I wanted to
clear them separately, I created a split transaction. The two journal
entries naturally ended up right next to each other in the other
ledger (in the opposite order than I expected). In the Auto-single
mode, I was unable to select the second JE on the screen: clicking on
it sent the cursor into the first JE.
Best,
Dylan Thurston
