Yeah, it's totally weird, not sure if anything changed with the OS, but I don't think there was an update between yesterday and today. Other than that, no differences software or OS-wise, at least that I'm aware of.
It doesn't register any presses and isn't responding in the read scan mode to CTRL, ALT, etc. It does work within the window to load a file, i.e. I can type a file name in the windows window that pops up, but then no response when back in EoF. Totally bizarre. I'll have to grab a cheap extra keyboard from work tomorrow and bring it home to see if it's a hardware thing, but it's the only thing that isn't working with the keyboard, so I'll be surprised.
Lastly, I tried another install (well, unzipped file) of EoF and it's having the same problem. So, something is obviously not right...
I appreciate your help and getting back to me about it. Let me know if you think of anything, but don't lose any sleep over it. I'm more curious what happened at this point and figured I'd ask if you've encountered this issue before.
