That's interesting, Sted. I've had textease working on my Windows machine for donkey's years, even after a Windows 10 64-bit upgrade. I've just re-installed Windows 10 because of speed problems, and now I can't get Textease to load from DVD. It's a 16-bit version, and I don't know what version my original installation was.
I have hundreds of textease files that I use regularly, and I'm stuck for a solution. I'm just making a flashdrive installer of the 32-bit Windows-10, and will try that, but if you have a better idea I would be very grateful to hear from you.
