In some of the scripts, specifically the Premiere Hotkeys script, the mouse will not move back to its original location. This is likely due to an issue with the mouse move function, but could alternatively be linked to my own monitor setup and mis-recording of xpos and ypos coordinates.
This issue will likely be fixed with the 1.0 release of code, which is due to hit around the end of April alongside the video which explains every single hotkey in detail.
