Deleting space after expanding

[Saoirse Canery]

When I use an expansion without ending it with punctuation, FF has started deleting the space needed to make the expansion work, but if I try to get around it by hitting space twice, it inserts two spaces.  This didn't happen until my second day using FF, and I can't figure it out.  No settings have changed.  Help?  Thank you!

You may want to reinstall the program using this link: https://www.nch.com.au/fastfox/ffsetup.exe

Before reinstalling the program, I recommend you to create a backup data file to avoid losing your information during the process.

Thank you for your prompt reply, elk!  Unfortunately, this had no effect.  As a matter of fact, a new problem developed.  Now occasionally when I'm correcting the problem, it is changing the text/paragraph formatting after I delete the word.  This is really a problem, and a bug I'd expect to find in a free program.  I wouldn't have purchased if it happened during trial.    Any other ideas?  Thanks again!

ETA:  I am now unable to get through 2-3 pages without this happening.  Restarting Word seems to fix it, but this isn't really acceptable to do this frequently in my line of work.  Ty!

Bump, please?  Still happening.  I have been unable to find a way to contact tech support, which is also kind of ridiculous.  Thank you!
