Regarding the slowness. It may help if you enable the hardware acceleration for graphics.
File > Preferences. Windows Specific category, [X] Enable hardware accelerated graphics.
This will be applied to any windows shown after the preference is changed (not already-open windows).
We are unable to have this enabled by default due to a small number of older graphics drivers which have trouble with this mode. I recommend everyone try enabling this setting for a better experience in JMP, especially if you tend to run JMP with maximized windows.
If you see visual glitches after enabling this, you may have one of the problematic drivers and would need to reset the setting to off.
