"Edit Image" does not edit the right image

Hi there!

This is driving me bonkers. I have three ongoing Captivate projects, all of which share one image library. Very, very often, when I try to edit an image from the "Library" panel in Captivate, things don't go as expected.

Expected behavior:

1. Find image in Library panel and select "Open With Photoshop."
2. Image opens in Photoshop. This is the same image that is saved in my Images directory. (e.g. the folder I have always imported images from.)
3. Make changes and save.
4. In Captivate, select image in Library panel and select "Update."
5. Updated image appears on slide.

Actual behavior:

1. Find image in Library panel and select "Open With Photoshop."
2. Image opens in Photoshop. But! The image is not the one from my Images folder. The image name (file name) is truncated, and it's been opened from an entirely different place. Here's an example.
   The file is named "Guide.jpg" and it's saved in "../Documents/Captivate Projects/Images." When I open it from within Captivate, it's called "Gui3.jpg" and it's saved in the deep depths of "AppData > Local > Temp."
3. Although I know it's futile: edit image, and resave it in my Images folder.
4. Select "Update." Image, of course, does not update.
5. Import the "new" image (though in fact the "new" image has replaced the original image in my Images folder, which I thought the project was using). 
6. I now have two images: one is the original, which points to the dreaded "AppData" version, and one is the one I just saved in my Images folder. In Captivate, they have the same file name, but the new one in marked with a "(2)."
7. Lose my mind.

Can anyone help?

Thanks!
