Hi fred, 64bit has been a lot of work but I have been working on it for quite a while now and it's almost ready. So the first v4 beta will have the 64-bit part.

I also want to improve the handling of long names in the scene browser like you're asking about. That won't be ready for the first v4 beta but I want to work on that during the beta test period. In the meantime it is possible to adjust the width of the scene browser panel to be wider by editing one of the text files that has the UI setup in it, please see here for some details on that: http://moi3d.com/forum/index.php?webtag=MOI&msg=5319.2 . The instructions there for where the file is located are for Mac, for Windows look under the ui folder inside MoI's main installation folder.
