I just downloaded a .Blend file and the number and letter hotkeys are not working. Things like the tab key still work. I open other files that where already on my laptop and everything works just fine. The file I downloaded is from my other computer and it works just fine on that computer with all the key input working but for some reason not when transferred. I have downloaded two versions of the same file, one with everything packed, and one just the file before packing. Both files have the exact same problem.
I am using version 2.78. my laptop should be fine, i7 processor, 12G ram, 64 bit operating system.
