START command only opens new window if .EXE is NOT already running

Question

So my Batch file command goes as follows:

@ECHO OFF
SET link1=google.com
SET link2=google.com
SET link3=google.com
START /MAX vivaldi.exe %link1% %link2% %link3%

When I double click my .BAT file, it only opens a new vivaldi window if there isn't one currently running. If I already have a vivaldi window open it will simply just open links 1-3 in new tabs on top of the tabs I already have open(and maximize the window if it is not). I was under the impression that the START command should always open the .EXE in a new window unless the /B flag is set(which it is not)?

Replace your last line with:

START /MAX vivaldi.exe --user-data-dir=c:\temp %link1% %link2% %link3%

You could create a dedicated folder rather than use C:\temp, and specify the full path to that instead.
