Performance issues

Modules / JaxCore freezing & making mouse jittery and unresponsive

This issue mainly happens when a part of MetroUI (e.g. Default start menu / taskbar calendar) is active, preventing JaxCore from taking focus from these UI features. It might also happen when simply trying to load core using a desktop icon.

To fix this issue, load JaxCore using Right click --> Configure in core --> Home instead of using the Taskbar icon, and simply try to avoid launching core modules when a part of metro UI is active. When that happens, simply click on the desktop.
