Can Enigmail and gpg4win work together?

I write a message and sign it with Enigmail and WinPT says it has a bad signature if I try to verify the received message (Enigmail verify it OK). And to the contrary if I sign a message with WinPT the received one is well werified by WinPT but not with Enigmail. Why? It uses the same GnuPG… Have you any suggestions how to correct it? TX! H.
