Hi Peter,

Have you tried putting a breakpoint at your "launch" line so you can see 
what's in the tFilePath variable? It may not contain what you think. At 
least that's how it sometimes works for me.

The idea is to be able to store the locations of images and display them in the default image app when they are chosen from a pop-up list. In the standalone, when I select the name of the image from the pop-up, nothing happens.
