Which pinentry program are you using?  Copy and Paste is only enabled in 
pinentry-qt4 (you can rename pinentry-qt4.exe in your installation folder to 
pinentry.exe to make sure it is used if you have not configured it in your gpg-
agent.conf otherwise)

Kind of. As said above, pasting the passphrase is enabled in pinentry-qt4. The 
problem is that internally we jump through some hoops to ensure that the 
passphrase is stored in secure memory. If you just copy / paste it you defeat 
that and make it extremly easy for other programs to grab the passphrase. . 
E.g. if your clipboard contents are swapped to disk or if you hibernate it 
will even be stored on the disk.

So we advise against copy&pasting your passphrase.

As I have written above due to many requests to have the possibility to do 
this. (And ultimately we can only set sane defaults / recommend stuff) We have 
enabled copy&paste for pinentry-qt some time last year.

So it should work.
