Dear William,

this can also happen when a Stata file becomes corrupt.

One sign for that is when you put a value in the editor in one of the
columns, it mysteriously shows up in several others as well (not
necessarily in the same obs). Look for a str0 bug description I posted
sometimes ago to the statalist for symptoms (str0 is an invalid type,
and Stata goes crazy when openes a file with it). Check if your files
are being produced by Stata or another program, like a converter of
some sort, or another statistical package.

Test your files, try them on another computer. If any converter is
available, try to convert the Stata files to another format, to see if
a converter complains.

To check your memory you can disable "quick-boot sequence" in the bios
of your computer and it will do a thotough check of your memory. It is
highly unlikely that your work with other Windows programs can be
stable if the memory is failing.

Best regards,
   Sergiy Radyakin
