AutoHotkey to the rescue (sort of); here is a short script to be run in the AutoHotkey free download script engine, which temporarily converts full stop to a space, and also converts colon to a full stop. If you want to type colon, that's too bad ;-) You could use slides but I already have all the slides I want!!
On the other hand, this cure may be worse than the disease!
