I've experienced this, too. It could be a side-effect of a recent
presumably security enhancement disabling qvm-copy-to-vm and
qvm-move-to-vm, replacing with qvm-copy and qvm-move, requiring the user
to enter the target domain in a dom0 confirmation popup window.
using qvm-copy-to-vm (within a VM, not dom0) gives the following message:
```
qvm-copy-to-vm/qvm-move-to-vm tools are deprecated,
use qvm-copy/qvm-move to avoid typing target qube name twice
```
If it helps, you can copy from the dom0 dialog window to the dom0
clipboard and paste over and over. But I agree, it makes GPG
encrypting/signing everything by default (which is what makes enigmail
so wonderful!) too painful to use. A bug report --
https://github.com/QubesOS/qubes-issues/issues/3470 -- will hopefully
help find some security-minded compromise to help users encrypting many
emails.
