I could find no way (under Windows) to remove a specific plug in. I decided to completely uninstall Cropper and then install a new copy without adding any extra plugins. Once I ran the new install I noticed that there were two plugins added by dafault -
Clipboard Format and JPEG Format.
My prior installation also had 2 plugins that I added after the Cropper install - Send To E-Mail [Jon Gallowy] and Send To Amazon [paltman.com]. I did not add those plugins back this time around.
This time, I was able to have all my settings changes saved in the config file. The program is working perfectly (and I'll have to wait on the F8 shortcut key fix).
I noticed an option during install, by the way, whether to make the install of Cropper for the current logged on user or any user of the PC. I selected "Any User", which was not the default. I cannot honestly remember if I had changed the default
during my first install where I had saving issues. I am thinking I may have left that option alone. So, that may or may not have been a factor.
So it could be the clean install without those two extra plugins or it could be changing the default for who can run the program during the install.
