The transform number input code allowed to keep typing forever. That's nice but the code uses floats to store values, so there's a limit of 7 digits resolution to take care of. I've added this limit now, it will stop when the 8th digit was typed, giving a range of 100 million, quite OK for Blender measures. There was also a short in use for values between 0 and 1, causing an error when you try to type like 0.99999. Here I've added a limit of 7 digits.
