How do I make the remaining time pop up screen to show on the center of the screen?
The handyCafe Client receives the data from server and keeps the sync between them.

However, you can issue a notification to all or each computer with the remaining time. Right click the computers in the administration area and follow the instructions.
that is the trick. It better for the HandyCafe team to consider this in a future update.
