GpgEX hangs Explorer & not symmetric encrypt

Hello. I’ve installed Gpg4win 2.0.0 but Explorer hangs when I try to decrypt or encrypt a file with GpgEX right click. I need to close the Explorer window and then I can see the dialog for encrypt/decrypt (Kleopatra).

Another problem is that GpgEX have no option for symmetric encryption/decryption. I’ve used GpgEE with Gpg4win 1.1.4 and I’ve several files symmetricaly encrypted.
