Hello, I have the same problem :
-Endnote X1 on Vista
When I attach a file I can’t re-open it.
I think the problem comes from the link used by Endnote X1 : "\D:…\mydoc.doc "
It consider that my file is on a network drive (" \" ) whereas I use a local drive!
For example when I put the link present in the error message in the run window (start > Run), Vista don’t find it because it is looking on the network (my DNS doesn’t know “D” ) instead of in local !
The good link should be : “D:…\mydoc.doc”
Please if you have any response tell me, because if I can’t use file attachement => I can’t use this tool…
