Here's a history of MCP:
0.60
----
v.52:
-Not showing startup/launching apps for some people fixed
-WinLogon portion moved to mcpstub.dll
v.51:
-SmartStartup no longer launches during safe mode.
-
Purple icon issue fixed
-'Startup Manager 1.0' changed to 'SmartStartup'.
-SmartStartup can now be hidden by pressing the
Escape key. Components will still be launched,
however the status will not be visible.
I think that MCP install might be doing it...you can try this if you want and see if it corrects your version, although an SDC un-install, re-boot, re-install would probably be more successful...try this http://mi.stardock.com/private/mcp_notfound.exe and if it doesn't fix it then do the SDC song and dance.
