Refresh File System (F5) in Directory view not working OSX

[[PL]]

Hello All,

I have recently upgraded to ASP2 on Mac OSX 10.9.5 (mid 2009 Macbook Pro).
I use a Nikon D800 tethered to my machine via a 3rd party app called Sofortbild.
My NEF files go straight into a directory that I have ASP2 pointing to.
When I press F5 to refresh the file system in directory view, the images do not show up.
They only show up when I click out the directory, then click back in.

This same process was working prior to upgrading to the new version of ASP2.

Any ideas would be greatly appreciated.
