In some instances, users cannot save their resize preference after closing the HyperTrader app by pressing the x button. As a workaround, please follow the instructions below for the correct OS system:
macOS
When you click on the x button in macOS, it doesn’t completely kill the app. This is macOS behavior, and we can’t do much about it. What you need to do to make it work is, to resize your window and then press cmd+Q, which will quit the app completely and then will remember your window size when you relaunch the windows again.
Windows OS
What you need to do to make it work is, to resize your window and then press Alt+F4, which will quit the app completely and then will remember your window size when you relaunch the windows again.
