Bonjour Pierre, yes that means you have a keyboard shortcut that is calling a custom command that is not installed.

Currently when you install a custom command such as Pipe, Autorotate, etc... - those get copied into the \commands subfolder underneath MoI's main installation folder.

When you install a new beta release, it goes into its own new installation folder, and its new \commands subfolder does not have that custom command in it.

So you will need to copy those command files (usually there are 2 of them, one .htm and one .js file) into the \commands folder in the new installation to make them work.

Shortcut keys are defined in the moi.ini file which is located in a separate centralized place (under c:\Documents and Settings) than the main installation, so those definitions and settings will automatically persist between installations.
