The last "Save As" location/folder is not remembered in ArtPro.
Symptoms
When you save a file on Desktop and try to save another file, it jumps back to the Documents folder as the last location is not remembered.
Solution
The com.esko.artpro.plist file located in User Library/Preferences contains the information regarding the last Save As location and resizing the pop-up windows in ArtPro. ArtPro can retrieve this file but in some cases cannot read.
Close ArtPro.
Remove the "com.esko.artpro.plist" file from User Library / Preferences.
Reboot the machine.
Restart ArtPro.
User Library
User Library is a hidden folder. From Finder, go to Go and by holding the ALT key select Library.
You can make this folder permanently visible in the Home folder by going to View/Show View Options and enabling the Show Library Folder option.
