Hello. I have one question to ask. When I try to modify a created layout file( using the 'e' key) , it says "file is not writeable." Do you know a way to resolve this? I would appreciate it if you could provide an answer.

hi @권미정 , could you try opening a new, empty magic window and there type

: load <name of your cell>

and then try editing?

Wow, it's working well! Thank you so much!! @Aleksandar Pajkanovic

hi @권미정 check if the file is open in another window. Also, check if you have writer permission with

ls -la

see if there is

w

for your user. Regarding the Application Error, I really have zero experience with something like this...

@Aleksandar Pajkanovic Wow, that was correct, thank you so much!
