Zenju, that and reinstallation of 11.11 fixed it.

Thanks.

I knew it had to be one of those "sloped shoulders and flat foreheads" things.

I select a .ffs_gui, single-click "Synchronize". It scans the folder pairs, and then instead of pausing and displaying the "Start Syncronization Now?" dialogue box with a summation of the "new, update, delete" files, it goes directly to synchronizing the file pairs.

Running Linux Mint 19.3 and FFS 11.11
Suddenly, my .ffs_guis are behaving like batch files. Running them manually, the file list is built and then it goes immediately to synching. I can't find any setting to stop this.
Reverting to 11.10 no help.
Version 11.11 on a Windows machine works fine.
