Strides Logger [Delphi]

For the delphi developer wanting to make custom chams, this tool will help in finding the strides, Hooks not included....

Screenshot
Usage:
Insert - Logger Off/On
Arrow Up/Down - Navigate
Arrow Left/Right - Decrease/Increase Value Of Selected Item
NumberPad 7 - Strides Off/On
NumberPad 8 - Nums Off/On
NumberPad 9 - Prims Off/On
