FactoryTalk View SE VBA Single Thread

Hello,

I understand that VBA is single threaded. In factory talk view SE though, since each graphical screen hosts its own VBA project, does this mean that if im running 10 screens with VBA scripting, each VBA project is running on its own thread? or does each VBA project wait for the other VBA projects to complete execution before executing?

In other words do i have 10 threads running because i have 10 graphical/vba screens running? or do all 10 screens run in a single thread?

Thanks
