I’m using version 1.5 (downloaded and installed in September) on WinXP. When I try to move the projects in the list, they are copied and I can drag the copy where I want it but when I drop it, the copy immediately shrinks down and disappears. The original project is not affected.

I have not installed Klok at home but I will do that as soon as I have a chance and see if the same thing happens there.
