I use Visual Source Safe as my version control software. Therefore all project files were set to read-only. I made changes to my project files in FireFly and saved the changes. When I opened up the project later to work on my project some more, all of my changes had disappeared. Upon investigating, it turns out that since the files were set to read-only, the changes were never saved. But no indication was ever given to me that my changes were not being saved. No error message was shown to me in the FireFly IDE when I saved the project.
You should consider handling this like VB handles the same situation - when this situation arises in VB, an error message comes up and tells me that the changes could not be saved because the file is read-only.
HTH
Yes, good idea. I believe that JellyFish Editor checks for read only files but it looks like FireFly may not. I'll will add the additional check.
