Cannot Update Menu

My menu of scripts wont update when i add new scripts and hit the Update Menu button, i have no idea why. Im adding the scripts into the same folder as bundled scripts and also can run the scripts fine if i open them in the text editor.

had a similer problem only mine was with the import scripts. if there was anything other than .py (or .pyc?) files in the folder the list wouldn’t update completely. I have a habbit of keeping zip files, so that and a few superfluous folders were to blame.
