Editor bug using delete [VIDEO]

Hi all,
This bug happened to me twice recently... when I wanted to replace an instruction in a program...

I am in the multi-line editor to replace an instruction
I insert a new instruction just after
I go up once (up arrow)
I hit delete (backspace arrow)
=> both instructions are deleted!

It happened when I did the "up" + "backspace" sequence...

It happened twice in few days, I suspected a problem with the backspace key, but no... it works just fine with no "double delete" when I edit X or Alpha register for example...

Sincerely,
Boubker.

(it's an unlisted video, you have to get throught the url to see it)

Seems to be repeatable replacing a LBL instruction!

Hi Boubker,

See viewtopic.php?p=18374#p18374 for more information.
I guess your finding is similar to the problems reported there.

Best regards,
Thomas

I concur. Seems if you add a label LBL(and I think other instructions with a second parameter - even with RCL 00 for instance) then add more lines then up or down line and then <- (backspace/delete) then multiple lines will be deleted.

I think the answer lies in when that label (2 parameter instruction) is added then a bug will happen at any time after when backspace is used on a line. Once that bug has been used then all is normal until another label is created.

This bug is easily 100% reproducible.

Best regards
