Just include a New Window script step before you switch to your map.
Thanks LaRetta. I know nothing about scripts (unfortunately). When I am in layout mode and I click on my map button, the button setup window appears. I don't see where I can add a script, the only option available is to specify which layout to open. What am I missing?
You can use Manage Scripts to create a script that has steps to open the new window and go to the new layout as LaRetta described here. Then you can use button setup to select the perform script action to perform the script that you have created.
Since this is new to you, you may want to read up on them a bit first or take in a tutorial on the subject before trying to do this.
Thank you PhilModJunk. I will check out the tutorials first and then try my hand at it.
I really appreciate your time.
