Hi gumshoe! I can't see your "for instance" but I had a similar problem that drove me nuts for a while - it just might be the same thing that's affecting you...
Double click the object that you want to be clickable.
When the "Edit image" window opens up, look down the left hand side and click on the bottom icon "Set collision polygon"
Look at your image in the editor and make sure it is fully covered.
If not, you can right-click for some automatic options or else drag and drop the little red squares.
Hope that helps.
