The starting coordinates (stored in i_x1 and i_y1) are calculated correctly.
But the coordinates of the pointer while the mouse button is being pressed (stored in i_x2 and i_y2) are not being calculated correctly. However I'm using the exact same method to calculate both.
If I use Screen2Local instead of Global2Local (in the calculations of the coordinates while the mouse button is being pressed), the i_x2 coordinate is calculated correctly but the i_y2 coordinate has a negative displacement.
Can't they be calculated the same way?
Please, please, please, someone help me.
