Just installed Panther (on my wife's machine, as it's a little less mission critical) and discovered an annoyance.
Installed the Estonian keyboard layout (that's where I live), which is from the "CentralEuropean" script family. But that seems to result in me not being able to uncheck the "US" keyboard layout and leave me with only Estonian. Playing around I have discovered that I need to have at least one keyboard layout of the "Roman" script family around.
I wouldn't mind the US being there, but the operating system seems to just switch back to US for no reason annoyingly often, and it also defaults to US on restart/login, although I had last set it to Estonian.
Does anyone know of a cure to this? The CentralEuropean.rsrc is a binary file too, so I failed at attempt trying to hack and change Estonian to be a "Roman" layout.
