- Save a file
- Then select 'save as...' and use a different filename (see the dialog screenshot)
- Error. See error screenshot.
It seems PE has still selected the previous filename and uses that as the base folder.
Workaround: in the savedialog, go a folder up, then click the folder you want to save in (this deselects the current filename, preventing the problem).
Could be Mac only. 0.3.100.
