Thank you for looking into this. If you mean I will have to set up the XBMCLauncher development environment and recompile the sources, I'm afraid it goes a little over my head

Heh, no worries. I followed the links on the first thread, took me 10 mins to get it all up and running. Pull the code, make the changes to XBMCLauncher.ahk only, recompile to get a new .exe (just right-click on the AHK file to do this). Then you need to go into Program Files\XBMCLauncher, rename the current .exe to something like .exe.old, and copy your new one in there. You won't be able to delete the incumbent one as it's still active. Reboot to pick up your new .exe file.
