entering numerical values

[Bling Keeta]

I don't know what I've done accidentally.
When I type in 45 for 45' high wall, I got 5' 4".
I need to move my cursor behind 5, and type a 4 in order to get 54'.
This only happens at one of my computers, and the others don't have the problem. Is there a hidden setting somewhere?
Can anyone help? Thanks.

This sounds like your system's character input changed from left-to-right to right-to-left. That must be a system settings that may have (or may have been) changed somehow.
I am not on Mac so I don't know where to check it and set it.
