Can't reproduce: opened a new project, added a text object, then duplicated the layout. The first text object has UID 0 and the second UID 1. No .capx provided so cannot investigate further. Note the r241 download link is right there in the website footer.
The issue is mainly to do with the fact that naming the objects after they have been duplicate. Yes the UIDs do change eventually but only after a close project and reload but my problem is that when the new UIDs are assinged, when I then change an objects name on the duplicated layout, it still re-names the original objects name as well. I can provide a capx but it will not really clearly show the issue as you need to see it happen as a possed to seeing it after it has happened,
Also if I download the newer build , is there anyway of installing it separatly to the existing build because I could not see an option to do this.
