IE6 & OE6 --

Something recent has happened to OE6 and tif files:

If I receive a tif file (as opposed to a tiff file) attachment in OE, I can
no longer save it to file or open it; it is grayed out. This has not
happened in the past.

Also, if I attach a tif file to an email I send via OE, I cannot open or
save the attachment when I look at it in the SENT folder; again, it is
grayed out.

If I attach the same file using Gmail, I can access it with no problem from
the Gmail SENT folder.

What is the problem with OE??
