no save game corruption, only using visual mods, tried "SHV 1.1 Key Commands and F1 Help Layout", but was having the issue previous to this mod, was actually hoping it'd fix it.
yes it is logitech ,ex 100, but i don't have the fn toggle lock, works the same as using shift or ctrl. ironically using fn brings my shortcut applications right out.
tried a reinstall as well, no dice, still not working.
its frustrating because i had a really nice screenshot lined up during my recent resupply.
