I would try Irfanview, a free image editor and viewer from http://www.irfanview.com/ . It handles most image file types, including TIFF files.
About the program that keeps crashing. If you mean the Windows default image viewer then I suspect that this uses "Explorer" in some way and Windows Explorer, (including My Documents, My Computer, and so on), often has problems when attempting to display image files as thumbnails or icons that are corrupted.
Irfanview manages to handle such files better than Explorer, but corrupted files can still be a problem. A test would be to open Windows Explorer and change the view option to Icons or Thumbnails, then try and list the TIFF files. If Explorer crashes, that is a sure sign there is a corrupt file in the list. Change the view option to Details or List, and it will list them without problem. It is only when Explorer is attempting to render the images as thumbnails or icons.
Hope that helps.
I have a laptop on Vista that opens a lot of Tiff files for work purposes. The problem Im having is that the built in default windows program keeps crashing when I try and open certain Tiff files (reason unknown).
I was wondering if there was a recommended viewer which also allows you to print?
