Between myself and my MIS department we have installed close to 30 systems mostly set up on Windows 3.11, but also several Windows 95, and Windows NT systems. After making sure we had QuickTime for Windows installed we have found it to be fairly stable on all 3 OS's and on a large variety of machines. Does it ever crash?? Yes it does but not a whole lot more often than Word or Excel. Our users primarily use TF for Email, and to prepare customer quotes by download product images. Some have been using it for several weeks now. I am very pleased that b7 now handles attachments and supports the address book. Something that was sorely needed for us with over 80 outside salesman.
