Thanks Ben, I've spotted it though and am currently in the process of downloading the pup. I'll give it a try in a bit.
Looking at the release notes it doesn't mention the XTs though, but hopefully this works. I don't suppose you know if it covers an Explorer issue where Explorer itself crashes when PGPTray is loaded after right-clicking on certain files? I did have a support case open for it, but I've not heard back for a while - I won't pester them if you know, but otherwise I'll chase (it's with our supplier who logged a case, so I don't have a case number for reference, unfortunately).
