I got annoyed and went to figure it out myself. Usually localization information is contained within the info.plist file for a Macintosh application. Not so for mLaser. Instead, its controlled by mLaser.ini in the MacOS subfolder of the application bundle. In that WINDOWS initialization file there is a section called mode with a key of language which is, by default, set to zh which is the ISO identifier for Chinese locale.
This is not Platform Compliant. Multiplatform systems must interrogate the host operating system instead of setting defaults. Either that or there should be locale specific builds as part of the build process.
The Doc implies that its gonna be easy. Luckily I’ve got the right background to figure out issues such as this. What about a kid who got the kit for Christmas?
