Bug reports!
When I browse for the files for anything, photo, program, icon, etc. it uses <APP_PATH> but then uses the absolute/full path. So for instance, it looks like this:
Photo.File=<APP_PATH>\C:\Folder\image.jpg
And then it still tells me the photo can't be found.
And it's not very helpful that I can't manually type/edit the path in those input fields. They're locked and the only way to edit them is through the Browse button, which populates incorrectly with the full path.

Also, when browsing for a file to run, it defaults to htm or html files, even though the Type is set to Filename. And how come it won't let me save it so I can do incremental testing? There's only Save As, which gets a little annoying since it creates the autorun.inf and copies CAR.exe over every time, asking me if I want to replace them.
