RE: Smartlist window won't open for specific user.
Here is what worked for me. Prior to trying any of these tips, I tried to run Smartlist, did not see it open but I did see it running in Task Manager. I then applied these changes to the DEX.INI file
WindowMax=TRUE
NoteWindow=-123,-108,1366,719
WindowPosX=223
WindowPosY=16
WindowWidth=808
WindowHeight=768
After making these changes, Smarltist still not appear but this time when I hovered over it I got the options that Victoria mentioned and I was able to click Maximize. Smartlist would then open and then close and open again. In my case I think is was the WindowPosX, it was a negative 2. I think this made it open outside of the normal screen parameters. Hopefully this will help others.
