Issue #1:
Images put on the clipboard can't be previewed anymore.
Steps to reproduce:
Open Paint, make some squiggly lines, select all, Ctrl+C. Now you have an image on the clipboard. Now try to do 'Show Preview Popup' using ClipboardFusion. Nothing is displayed.

Issue #2:
Putting the exact same image on the clipboard creates duplicate entries:
Steps to reproduce:
Open Paint, make some squiggly lines, select all, Ctrl+C. Now you have an image on the clipboard. Open ClipboardFusion's Clipboard Manager and notice the single entry for that image. Now, in Paint, hit Ctrl+C a few more times. Open ClipboardFusion's Clipboard Manager and notice the many duplicate entries for that same image.

Issue #3:
Pasting an image using Clipboard Manager creates a duplicate of it.
Open Paint, make some squiggly lines, select all, Ctrl+C. Now you have an image on the clipboard. When you view the Clipboard Manager, there is just a single entry in position 1 for that image. Now copy some text to the clipboard. Now in Clipboard Manager there are 2 entries: the text in position 1 and the image in position 2. Now open an application such as Word, and using the Clipboard Manager select the image in position 2 so that the image gets pasted into Word. Now have a look at the Clipboard Manager again. Instead of having 2 things in the list, it now has 3 things in its list. 2 copies of the image (i.e. the original one plus a duplicate that has just been created) and the text.

These are pretty basic things that don't work in CF 6.1. I wonder how come no-one else has noticed, especially since they actually go back several versions to before the final version of 6.0 was released. I've reported these issues to Support a long time ago, but to this day are still unresolved. So that's why I've now created a forum post to bring more attention to them.
