The main problem I've experienced is that on 3 separate occasions I've removed a right shared border only to find that the shared border disappeared from every page on the site even though it was still showing in design view on pages where it was supposed to have remained. The only way I could correct it was to open up FP2000, clear the contents of the shared border, re-enter it and save.
Editing a right shared border also seems to push the main text over the left navigation border.
No doubt these are elementary errors I'm making but at the moment I can't see how.
