Is there a way to avoid this?

I found the solution finally by using #SingleInstance option at beginning of file : Now at each run from notepad++, i have only one single instance of the edited script (only 1 green "H" on taskbar) that's great !

Cheers !

Hello i tried the script it works well ! But the only annoying thing is everytime i run the script from the same file, it open a new instance, that makes many scripts running at the same time, and so many green "H" on taskbar, instead of replacing the ongoing script. So i must always quit the tested...
