Rpg Maker Developers Group

I'm programming a glossary system that sorts characters by stats.
There is a menu to choose a character, then a page for each character.


The menu


The characters page.

And when I get to a character's page and want to press return, the game uses a command that disposes of the windows on the character's page to return to the menu, and then rpg maker shows me a disposed window error, while the window is clearly NOT disposed yet.



I can tell because to switch from one character to the next without going back to the menu, I use the exact same command that disposes the windows, and it works without giving me this error.
I checked with my command that returns to the menu, it is indeed the command that disposes of the windows that has a problem.

I tried it on a blank project, it returns the same error, so it's not coming from another script.
I just can't figure out why it refuses to dispose my window, and it's driving me crazy.

I need help.

Don't worry about the missing graphics, I added a script to ignore them, it's just so you can see the problems and the script.
The command that dispose of the windows is at the end of the script.
