I've noticed a similar problem saving .tif files in IDL and trying to
read them in PowerPoint (PC Windows, ugghh!). The dimensions get
screwed up. Perhaps this is a peculiarity with the .tif image
format.

Our system is Solaris 2.5, IDL 5.0 (noticed this with 4.0.1 also).

Anyone else have this problem?
