ya. i just downloaded the latest version and that is when it happened.

so now my xml file recovered from the .jar is 8 MB , i cant share the large xml file.

any idea how to get it back to the usual <100 kb size like in previous version  Grin


no worries now...... i managed to recover the xml due to a lucky resaving into a different file name....hahahaha.........so lucky.

attached is the xml

I just download your vector02.xml and it work fine in my EJS (ejs2006 version).

I will save my file to different filename when I want to make some major change to the code.
The problem might be come from logical error: for example: define variable x, and initialize it with 1/x.
This will cause ejs to hangup, and you might get empty file if you try to save file at that moment.

thanks for your help sir.

I will be starting another thread as magnitude of vector is not encouraged to be developed further until pedagogy and syllabus are sorted first on my end.

applet is here now
