Hi Mirabai and Hesky,
Thank you for your quick responses, and I apologize for my murky explanation.
Here's what I've done:
1. Download exe file and save to desktop
2. Click on exe file; Plover works beautifully; I can click on the P to turn it on and off
3. When I'm finished writing, 'X' out Plover
4. After that, when I click on the exe file saved to my desktop, nothing happens - nothing at all
5. Delete exe file
6. Go to Plover wiki; save exe file to desktop
7. Same pattern: I can use Plover once per download, but that's it.
If there's something I'm doing wrong or an easy fix, I would welcome your guidance. If this is mysterious, then no worries. I'll just keep using Plover in Ubuntu on my old lap top until the installable Windows version is released.
Cheers,
Amber
