Oooh, ouch. Due to an impedance mismatch between how TIFF stores 3D
data and how we store 3D data, 3D TIFFs are probably the worst format
to put your data in, because accessing it is so slow. See the "Getting
Data Into ImageVis3D" manual for detailed information:
http://ci.sci.utah.edu:8011/devbuilds/GettingDataIntoImageVis3D.pdf
As a quick fix: a series of 2D TIFFs, and then loading from a directory
instead of a file would probably work better.

The 3D TIFF converter was written for a specific collaboration, and I
experienced a lot of difficulty finding sample data on the web. Thus
I'm not surprised if there are lurking issues; can't fix what I can't
reproduce :)
I'd very much like to fix said lurking issues, though. Could you use
the "Report an Issue" feature (under Help) and attach one of the TIFFs
which is failing to load, please?
As a workaround to get you going ASAP, I'd bet the series-of-2D-TIFFs
is your easiest route, since you're already familiar with TIFFs. The
QVis, NRRD, BOV, and (of course) raw formats can be pretty easy too.
Thanks,
