I really did not wish to create an entire new thread for this.
perhaps it might be worthwhile considering creating a sub-topic "Winstep issues and questions?" I noticed how many of issues and questions there are under multiple individual threads.

ANYWAY

I acknowledge before asking that it may well be my inability to find the correct location for this before I ask.
QUESTION: Is there a setting somewhere that I have missed that allows use per user in Windows? For example, I have Winstep Xtreme and Nexus Ultimate on one computer. When User 1 logs in they get Nexus Ultimate only and when User 2 logs in they only get Winstep Xtreme? (It's fun with BETA's, I have to rename the executable in one of them).

I apologise if this is a dumb question. I found the only way was to turn 'automatically start with Windows' off on both which is becoming tedious to manually start every time and I accept it is possibly my lack of knowing where the correct settings are .

Hello BassdudeNZ...
From what I understand, you're installing Winstep Xtreme and Nexus Ultimate. There's no point, because Winstep Xtreme already includes Nexus Ultimate with all its features, so installing Winstep Xtreme gives you access to all the functionalities (Nexus Ultimate, Workshelf, NextSTART, Modules, Winstep Start Menu Organizer Pro). Installing both would essentially give you two versions of Nexus Ultimate, which might explain the problems you're experiencing.

Anyway, that's just my opinion...

Eh?! What Picco said.

If Xtreme is also installed just DELETE nexus-ultimate.exe from C:\Program Files (x86)\Winstep, do NOT uninstall it as that will remove things from Winstep Xtreme too.

Also, all Winstep applications store settings *per-user*.
