Thanks to all those who responded. Several suggested that the crash was caused by a bug with VM; UT would work with VM not running. A patch was created for the bug and is included in recent versions of MI. I am using MI 5.0 and thus the solution had to be sought elsewhere. Today's solution: Make sure that mapinfow.prj resides in the mapinfo installation directory. In my case it existed in several directories (Tools, ArcLink, ShapeLink) but the local root. The file could be accessed by several other procedures, and so hadn't yet appeared as a problem. MapInfo Tech Support identified this while investigating a seemingly unrelated problem with ArcLink. Hats off to Cindy, and thanks to Mike, George, Tony, Peter, and Rick Original message: ************************************************************** When trying to translate a *.shp file, UT crashes when the Projection button is pushed. Only resurrection on this NT system is to End Task. Once while doing so I found an error message window giving something like "out of disk space for temporary files". Given that there is actually plenty of disk space available, there must be some other source for the error. Any ideas? ---------------------------------------------------------------------- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
