We are running SharePoint Portal 2001 and when someone copies a .tiff fileto the Document Library via a web folder it appears to copy OK but when yougo to the document Library web part and click on the .tiff file the browserjust hangs on a blank page.
Having you tried downloading the TIFF? You may have an problem with thebrowser's association with a tiff viewer - or maybe the viewer it'sassociated with can't handle that format of TIFF.
If I save it to my desktop and click on it, then it opens in Windows Picture andFax Viewer. When I try opehning it in IE, I get a broken Quicktime Icon in themiddle of the browser page and IE hangs.
