Macros are recording incorrect mouse positions on some systems, leading to every mouse action being way way off where it should be. This may be an issue with the ConvertPointToAbsolute method but I'm not sure.

Okay, so tracked this to being down to Windows 10 display zoom factor (mine was set to 150%). This raises some interesting questions about detecting and mitigating the issues caused by this setting.
