Cant get rid of drawing 1 tab at startup

[johnw]

When I double click on a drawing file in explorer window that should be the only drawing that opens. No matter how I set the Startup setting or Startmode setting I either get the Start Tab showing up, a dialog box to open a drawing showing up, a drawing 1 tab showing up, or both the start tab and drawing 1 tab showing up (then the drawing that I double clicked on opens up).

Setting the two settings as I have on another computer in my office produces different results. The other computer only opens the drawing I double clicked on, while my computer continues to open a drawing 1 tab and then mine.

What should both settings be to not open a start tab or drawing 1 tab... and can a partial cui file that loads cause any of these issues? Since that is the only difference between the two computers I've tested.

Thanks for your help,

John

I’m using 2018.

This works for me
STARTUP 2
STARTMODE 0

My other computer is also 2018. Startup 3 and startmode 0 do the trick on that computer. If I click on a drawing file in explorer it opens up and no other tabs are open. If I click on the Autocad desktop shortcut the template draw opens up as Drawing 1. Perfect.

My computer with same settings, when I click on a drawing in explorer drawing 1 tab starts first, then my drawing opens. Very odd. 

Other computer has no partial load cui menu that we created, but mine does. That's why I asked why two computers with the same version of autocad and settings the same have different results.

My setting is same as yours, startup 3 by default, startmode 0 for no start tab and I'm using a custom partial cui as well... no issues so far.

HERE is some info about the issue.
