I think you have just confirmed that you were incorrect for saying that my statement was incorrect. Regardless of how many monitors I use, if Start11 forced start button to align on the left due to multi-monitor and if I have to use startallback to achieve the intended result, that makes my statement valid.
Imagine selling a software and saying it works, you just can't use multiple monitors. lol?
At best Startallback is a competitor program for which Stardock will have no benefit in making anything of theirs compatible with it.
You either use one or the other. You are ill advised to use both.
Shell enhancements should not be toyed with as they affect your interaction with your OS.
Two programs by two different vendors used at the same time to alter essentially identical areas should never be attempted unless you want to live at the coal-face of 'issues'...
Best example I can give is an old shell replacement [not enhancement] - LiteSTEP, that when it crashed all Windows could do was tell you to "reinstall Windows" as it had no understanding of the shell being used....
