The buttons on the CMAXS screen are off-screen and I cant click them.

Please try the following steps:

Change the display scaling on your PC: In Windows, you can adjust it from Settings > System > Display > Scale and layout. For small laptops, the recommended setting might be over 100%, but lowering this percentage might help display everything without being cut off.

Adjust the settings of the CMAXS connection tool (Go-Global): Right-click on the Go-Global icon on your desktop, go to Properties > Compatibility > Change high DPI settings.

If the item names are cut off, set it to "System (Enhanced)". If the entire screen is cut off, set it to "Application". This may help display everything correctly.
