The editor displays the errors. I'm using 'e', which is a Windows equivalent to Textmate (basically).
Here's a fuller example. I open the SCP connection and navigate to the directory. I right click a file and choose "Edit". My editor launches with the file. The titlebar shows the path to the file as "S:\TMP\scp10906\docs\faqs.php". I choose save (making no edits for this particular test) and I get a dialog box with a title of "e Error" that says "Could not save file: S:\TMP\scp10906\docs\faqs.php".
I hit Ok on the dialog box and get another with title "E Error" that says "can't open file 'S:\TMP\scp10906\docs\faqs.php.etmp' (error 3: the system cannot find the path specified.)". I hit Ok, and nothing else happens.
I go to Options -> Preferences -> Editors and change the editor to Crimson Editor, another editor that I use....
And it works. :? When I save it reuploads the file as it should.
Ok, so it appears this is a problem with the editor. If anyone has any ideas what or why this problem is occuring let me know, but I think I'll go ahead and post in their support forums. Thanks anyways!
