This issue has not been reported elsewhere before, and it is very strange. May the destination folder (or file) be write-protected?
The file is definitely not write-protected, since I am successful in saving it (though the editor window closes after saving).
Apparently the folder
is marked as read-only (I had little incentive to even check for this going in) -- though removing the lock makes no difference, the editor window still closes after a successful save.
If I have multiple files open in the editor, make changes to only one file and save it (either from the menu or with the keyboard shortcut, the effect is the same), the editor window ultimately closes in its entirety.
If I have multiple files open in the editor, make changes to
two or more files, then Save one of the files, the save is successful, but the file is closed after saving, and then CB prompts me to save the other file -- implying something is clearly
trying to close the entire editor window after the successful save. If I cancel at this point, the interface is left as-is, minus the tab for the file that was just saved.
Are you saving the file with the drop down menu, or using a key combo?
Have there been any modification/overrides made to the keyboard?
I get the same result either way -- save is successful, then the editor window closes.
One important detail is that when I save a file, the editor window's GUI refreshes after saving (yellow margin indicators turn green) and THEN the editor window closes (after some delay). If I try to close the editor window directly and save changes when prompted, the tab disappears immediately, then the editor window closes entirely after a delay.
Oh, right, that delay may be another important detail; see new attachment (unsaved at left, saved at right, moments before the editor window closes).
