That's extremely strange. Save is saving to Nirvana? Have you administrator privileges or do you work with a restricted user account? Do you have permissions to write to the file? (Of course, you must have, because it works with Notepad, but who knows!)
My suggestion: Download free Filemon
, unpack it to a local directory on your hard disk and run Filemon.exe. You need administrator privileges to run Filemon!
Click in Filemon on Options - Filter/Highlight
and specify in the Include
field instead of the *
the file name of the file you want to edit without the extension and without path. After activating the filter press Ctrl+X to clear the display.
Now start UltraEdit, edit the file and save it. Back to Filemon, stop the recording (magnifying glass icon in the Filemon toolbar), scroll up to top of the record and look if you can see something strange.
By the way: What is shown in the status bar of UltraEdit when you have open the file (file format, R/O)?
