The initial attempt read psoSelect.AllowSpaces = true;
I've been faffing about trying to make it work and thus the code I copied is wrong. Take my word that with the AllowSpaces = true, when I use the spacebar it's acting as though I want to accept the current command line contents.

If anyone can verify whether it works as expected on their machine it would be appreciated.
The text file will need to have values separated by a blank space and the block will need to be entered by typing it's name.
