Undo

If you undo after saving a patch, everything except the io boxes disapears…

hm can’t reproduce this. is it the same with beta14.9?

Havent tried 14.9, I just went straight to 15, it might be after save as, it certainly does it here!
No just tried simple save and it does it still, does save clear the undo buffer?
I’ll try 14.9 when I get a moment

The same bug was in v14 and still in 14.9

i tried to reproduce some strange undo behaviours but failed especially with this one described here.

i also tried to modify getpatch/setpatch behaviours, so that they don’t interfere with the undo history, so that you only can undo commands you really did by hand in your patch. but it seems to have strange side effects. so i postpone that to after node08.

I’ve had other undo errors, for example I’ve deleted a connection, then undone it and undo previous to the wire have undone but not the connection deletion. SOmething odds going on, but I cant get a foolproof example to show you yet!
