Delete of image from Network drive "appears" not to delete image

System information:

• Windows OS version: Windows 7
• ImageGlass version: V6.1.7.10 Moon Portable

To Reproduce

Steps to reproduce the behavior:

1. Run IG. Find images in child folders is ON.
2. Drag a network mounted folder containing images to IG.
3. Move through images. Delete an image (delete key or "send to recycle bin").

[Note: because it is a network drive, "delete to recycle bin" is the same as a permanent delete.]

Actual behavior:

The removed image still appears on the screen. However, the title bar, and right-click
menu both behave as if the image is not there.

Move through the images (possibly past the number of images pre-loaded by the image boost), then return. The "deleted" image may now show a blank window, but the image filename is still in the title bar.

"Refresh" has no effect.
"Reload image list" results in the "Imageglass cannot open this picture" error.

Expected behavior:

On delete, the image should disappear, should be removed from the image list, and the image display should advance to the next image.

Start by reproducing the delete flow with a network-mounted folder on Windows 7 using the listed ImageGlass version. Trace the delete, image-list, and display behavior, then verify that the deleted image disappears, is removed from the list, and advances to the next image without a reload error.
