Thanks for this. The problem is the file save dialog. This is the major difference between running as a Photoshop plug-in and stand-alone. When running as a plug-in there is no file save dialog needed.

It is very likely down to shell extensions that have been installed on your computer, and these get loaded in the file save dialog. I don't know if you want to try this, but you could find out which extension is causing the problem and disable it.
There is a program here http://www.nirsoft.net/utils/shexview.ht...nloadLinks for doing this. Just download the zip and run the program in it.
You can see the company name listed for every extension, if it's microsoft just leave it but if it's some other company that you don't recognise then right click and disable it. You can always enable it again if there is no change running Portrait Pro.
Alternatively, if you don't want to do this yourself, then you can select all of the extensions, choose file/save selected items, and then send me the resulting text file so I can have a look.
