OS: Mac OS X Mavericks, OS Version: 10.9.4
I drag a file from the Double Commander application to SE.
File opens and allows edits as expected.
On file save, SE raises an error dialog indicating that file can not be found.
Open same file using SE's File Open, and the write works fine.
I noticed the same behavior on B4, but I assumed that it was me.
Thanks,
