First, some notes as I try to get PSP X4 set up the way I like it. I figured I should record how to make the Edit tab the default workspace in PSP X4 so that it always shows up when I open the program. I hate defaulting into the Manager.
1. When PSP X4 first launches, it defaults into the Manage tab.
2. To keep it from doing this, I first switch to the Edit tab.
3. Next, select General Program Preferences (File > Preferences > General Program Preferences).
5. Click 'OK'. Now the Edit tab will be the default whenever PSP X4 opens.
