On one of my Windows 11 Machines I am having an issue in Windows Explorer where if I choose an image file, no preview is rendered. Please note that it does not say "No preview available", it simply shows nothing in the preview panel.
I noticed I was running a beta version of Dropbox on this machine, so I uninstalled and then installed the latest stable version. I did not delete the orphaned Dropbox folder; I simply reinstalled it and let it resynch against what was there.
No joy.
Here is what does work:
In Windows Explorer, select an image file that has this problem. Change the selection to another file and then select the previous file. Preview renders. You have to do this *EXACTLY*. It is not enough to select one file, then the next, then the next; you *MUST* select a file, select the next and then select the previous file.
That works 99.9% of the time. If it doesn't work, you select the file that won't render a preview. Close the preview panel and then open it again. And the preview renders.
I *CANNOT* go through every image of every folder I have in dropbox. Surely there's a setting someplace or some cache that needs to be cleared.
Any insights would be welcome.
