Guild Wars 2

Hello.

I have been using a Logitech Anywhere MX mouse since launch and have my buttons mapped this way :
Mbutton4 > $ > Heal(6)
Mbutton5 > : > Skill (7)
MWheelRight > ù > Nearest Target
MWheel Left > = > Next Target

Unfortunately, recently something has glitched, and nothing seems to allow me to use these extra buttons.
I have tried adding Logitech support for Coherent UI, ImmersiveCombatMode AND/OR GW2.exe to nbo avail. I recently tried using AutoHotkey to set up replacement settings, but GW2 was the ONLY program not to recognise the changes.

I usually use SweetFX and ICM, but disabling them both (and actually taking them out of the folder) changes nothing.

My Guess ?
I installed/removed GEMFX, but I cleaned it up entirely, so it shouldn’t be a problem. So I guess it might be linked to SetPoint (Logitech) or recent changes to the game client.
If anyone has an idea… this is kind of ruining the game for me…

PS : None of the tests I made in AutoHotkey went against the game’s policy : I had simple “one key = another” replacements.
