To reproduce:
1) In smart open, go to home directory and open any file in your home dir
2) In smart open, cd to a directory other than your home
3) Do File->Save as. The Save As dialog starts in the current directory instead of the original directory.
SE version 22 the save as dialog puts you in the original directory, and all other applications that I know of do this.
