We have 2 pc at home with a router. Both pc have the same IP. One pc runs on Vista and the other on XP.
When I double click on the other PC contact, nothing appears. I do not see the Stickit note editor window, so I cannot transfer a note.
Is there a way to realize the transfer ?

You’ll need to add both of your computers to the same workgroup in order for them to be able to contact each other. Here’s a link that explains how to do that in Windows Vista:

Once on the same workgroup, your computers should not have the same IP. If that’s not the case, then you’ll have to manually change one of them.

At this point, you should be able to see both computers in StickIt. If you’re not using StickIt 3.0.6, then upgrade from the following link:
