I use last SVN ScummVM, with Maniac Mansion NES Version, and Spanish language. I extracted the lfl files with the last scumm_mm_nes.exe
In the "Image 1" can see the "S" letter of other dialog, It stay on the screen until other letter overwrite this section.
I attached the savegame near of this.
Morover, if you got the "S", if you reload the savegame, you can see the "Image 2", with the borders of other room in the actual room.

Second bug has been fixed for a while, as for the first one, I need steps to reproduce. That is save _before_ wide text is printed and way to print it. You have to create new bugreport since new bugtracker does not allow to attach additional files.
Hu? Of course you can attach multiple files, you just have to click on "Add a file" (I admit the UI SF.net uses here is horrible, but it does work).
