Re: jigsaw query

You'll need to have a greater 'environment memory' size.
Afert lauching an MS-DOS window, left click on the upper left icon of that window; on the menu witch appears, click on properties.
Then choose the memory folder and set 'environment initial to 4096.
click Ok, close the MS-DOS window, open it again and it should work.

This part of memory is used by environment variables ( ie PATH, CLASSPATH and others ).
You might still have problem if you already defined too much variables. In that case, suppress some of it.
