I've just gone through my logitech settings, and they all appear to function normally, But now that I've updated to Win7 SP1, my hotkeys only work if I use the actual key combo defined by the program, it no longer recognises my logitech G-keys, despite them being mapped to the same keypress.. Could this be SP1 causing an issue, A need for a logitech update, or something related to Displayfusion?

Update: I've set both displayfusion and Logitech core to run in Windows 7 mode, with admin privelages (Last known working state), and still have no results. SP1 seems to have conflicted somewhere with either Logitech (Which can still load all my other programs via Gkeys), or DisplayFusion's hotkeys.

Keyboard is a Logitech G110, so a similar setup to most of the other G-series Gaming Keyboards.
Currently using LCore 7.00.291 to manage the G-keys.

I've also noticed that If I go into Setpoint (For my G9 Mouse), I can macro one of the buttons in the same fashion as the keyboard, for the same DisplayFusion Hotkeys, and they work fine.

Interestingly, I've just added some updates to my x64 SP1 Win7, and now it's joined my x86 system in no longer recognising the G-keys as hotkeys.
I'm trying to figure out which update exactly is responsible for the change at the moment.
