Normally when an Excel macro or an EasyInput script is running one cannot work with other MS Excel windows. This is because separate excel windows share the same Excel engine called Excel instance. The user can however run a second Excel instance. To start it follow the steps:
1. Click with right mouse key the Excel icon on windows taskbar. Excel context menu should appear.
2. Press Alt key and keep it. Click with left mouse click Excel icon on the context menu. Do not release the Alt key! Keep pressing it!
3. When popup window appears, confirm that you want to start new Excel instance. And that is it!
