I am using Processer Hacker 2.39.124 in vista sp2.

When my computer starts up,it shows 2 windows in the systray.

When I click on on exit in one of them, both of them exit.

When I click on Process Hacker in programs, it brings up two windows in the systray.

Is there something, I am missing in options?

Are you in the wrong settings and you run two independent copies of Process Hacker. You can copy my settings and I think you will work. Just see if you have any startup (group Startup, plug Windows \ Run, task scheduler) double entries Process Hacker. If you find, remove everything, and when you set the new settings Process Hacker himself prescribe it right.

I set the options as shown in your picture.
No good.
Process hacker only shows on instance of itself running.

I set it up to allow two instances of process hacker running.
Now I see 4 windows on the systray.

Hmmm somethings not right here.

Did have have multiple tray icons enabled.
I just figured it out last night.

Don't have then enabled any more.

Thanks for your help.
