PDF Icon changes to blank in Dropbox folder

Strange enough, the PDF reader icon corrupts in my Dropbox folder on my Windows 8 machine. I am using Windows 8 x64 Pro.

If I change the "open with" to some other reader and then back to Adobe Acrobat Reader, it shows the PDF icon and preview of the PDF file. But somehow it MAGICALLY corrupts sometime later and the PDF file gets a blank icon. Possibly corruption of thumbs.db in Dropbox during synchronization?

This screenshot is in the root folder of my Dropbox folder on my Windows 8 machine.

Solution 1:

They just released V1.4.20 which is the first version with Windows 8 specific fixes (notification area icon for example).

If this version does not fix it I suggest you wait a bit as it seems the dropbox team is a little late to win 8.

I've seen numerous other bugs floating around the web when installing the OS so I think it is just a matter of time.

Tell me if this version works for you!

Solution 2:

Try changing the default viewer for the PDF to Reader and then back to Adobe PDF. It fixed a similar issue I had. Also rebooted due to Windows Updates. Was either the update or the default program switch that kicked it in.
