[Zope] Does SiteRoot Interfere With Copy-Paste?

I have encountered a peculiarity and I'm having trouble understanding it. I have a folder on my site called "learning" where I experiment with stuff I'm figuring out. When I get something working there, I want to copy the resulting object(s) and paste it(them) into another folder on my site. This works fine except in one of my folders. The only difference I can see between the folders where it does work and this renegade is that the folder where it doesn't work has a SiteRoot and the others don't. In this folder, the Paste button just never appears. Everywhere else on the site, it's fine. Anyone got an insight? -- Dan Shafer, Author-Consultant http://www.danshafer.com http://www.shafermedia.com
