This bug has the same symptoms as explained in an old post by robinsiebler (Bug w/ TC 6 and Irfanview?), but a solution was not proffered (the topic took a slightly different direction when franck8244 posted a year later):
Given:
1) TC and IrfanView (or XnView) (any versions)
2) Any Clipboard Viewer which copies CF_DIBs (also maybe CF_BITMAPs), from the Windows Clipboard such as ClipSpy or Ditto.
Symptoms:
- Lister View or QuickView of images show up in binary view instead of image view. If the image is opened directly (e.g. with IrfanView), they display normally.
- Repeatedly pressing F3 and Escape on the same image will sometimes properly display the image.
- In QuickView, moving the cursor to other image files does not change the QuickView Panel's contents.
Analysis:
It looks like the Lister uses the Clipboard for communicating with IrfanView / XnView and that the Lister has some timeout or just fails on OpenClipboard, since the Clipboard Viewer is reading it first. Perhaps the solution is to try to open the clipboard again or after a brief timeout? I think the QuickView should also be updated to the file under the cursor regardless of the failure of the previous file.
It is a minor bug, and, as I mentioned, Lister plugins work fine, so I'm using Imagine now -- also because I don't want all the images I view copied by my Clipboard Viewer. In this sense, the bug doesn't need to be fixed, but hopefully if anyone else runs across it, they'll find this post.

Aside from the bug:
- Does TC's "Find Files" -> "Find Text" using RegEx work with binary files? It only seems to properly search text files.
- I do have a slow computer (K6-2 400), but I just thought I'd mention that sometimes the "Find Files" box takes a long while to open (7 to 20 sec) and close (7 sec).
- I recently had cause to filter or sort by the "Created Date" rather than the "Last Modified Date" of files. Is this possible with TC?
Thanks for a great program.
