After using the Merge function initially, PCB1(in red) is on top of PCB2(in blue).

Thus, the user can view status changes of PCB2 with respect to PCB1.

However, when PCB2 is covered by a polygon of PCB1, etc., it can be difficult to view the contents.

In this case, click once on the PollEx PCB window and press the “Tab” key.

Each time the user presses the Tab key, the locations of PCB1/PCB2 will switch.

When clicking on the PollEx PCB window, please click on the Title Bar.
