Fixed with gpg4win 3.1.9.

Thank you very much for your quick action!

Hi Andre,

Hi,
as usual, thanks for your help.

The reason for this is the change to Kleopatra that the columns are configurable ( 4847fcc27afc8101752de82b0dd1f5fee027695d ). In the process we added additional columns like origin and to hide the "summary" column that the line edit for the recipients use we gave it an index number that was higher then our internal column count.

Thank you very much for the report. I can see this problem myself. It is strange because the code for that has not changed since 3.1.7 so it must be some sideeffect.

I'm having a very similar problem in 3.1.5! Randomly, when I try to view a PGP-signed e-mail, nothing shows, both on preview panel and when I open the message.

File->Save As now works for crypto mails. It saves the encrypted message.

This works now, the hidden BeforePrint Event enabled us to detect when a print happens and the old code to do blocking decrypts enabled the actual printing.
We also do not print "our categories" (encrypted message, level x trust),... anymore, even in quick print.

I did forget to mention that the key I'm using is 4096 bit long

I was creating a tar archive with 7-Zip on my Windows 10 machine. After the creating was completed I was encrypting the archive like so:

Just to clarify, you were able to decrypt and extract it without error? Which tool did you use to extract the tar archive?

The change in message class did not help.

Works for me
