Hie again Stu and Al, Stu...I followed your suggestion and I think you were right about the hidden attachement. I managed to save the (invisable) attachement "Pictures ToExe registration". However, when selecting this file for the registration procedure I get the message: "invalid or damaged key". Seems problems never end... I realise it was a stupid move to include my key ID in my previous message (I was not aware this was the real thing). But how do I remove it from existing message? Mzee
