Yes. To find out who sends it I did a little hack which would dump the 
call stack to a file when calling World>>install and it turns out we're 
calling it three times in a regular startup sequence:
1) Via AutoStart>>checkForUpdates
2) Via AutoStart>>checkForPluginUpdates
3) Via ProjectLauncher>>startUp.
The Right Thing (tm) to do is probably to add PasteUpMorph to the 
startup list and have it handle the initialization of Morphic.
