Clear description of the problem - try and include as much information as possible, including what button and mappings you are having problems with (if applicable).: the mouse has 2 buttons on its side, mouse 4 and mouse 5, and i wanted to chord mouse for with left click to copy and right click to paste. right click chord works as expected but for some reason left click chord is reversed: gotta hold the left mouse button and click mouse 4.

How exactly have you set it up? Do you mean you are chording button 4 and in the button 4 config, setting the left to copy and right to paste? Or are you chording the left button & the right button and then using button 4 to copy / paste?

Do you mean you are chording button 4 and in the button 4 config, setting the left to copy and right to paste?

yes.
mouse 4 -> button chording -> left click -> copy. same with right click. but left click works as if i went left click -> button chording -> mouse 4 -> copy.

That is a bit weird, can you PM re email me a copy of your settings (use the Save Profile button to get it).
