TARGIT in multiple windows
Make it possible to open more windows with analyses at a time. This way you are able to compare the data in analyses or copy and paste from one analysis to another at a time.
In the upcoming 2019 Update 3 release (due late October 2019) you will see Tabs. With Tabs you can open as many documents as you like in one client.
You can indeed open multiple TARGIT clients at the same time. Up to three simultaneous TARGIT sessions are allowed per user. This is often used to copy / paste from one analysis to another.
