Hi Lookang,

yah, i'm actually "stuck" in a local sec sch trying to push IT initiatives for physics within my dept.

Haizz, it's really a tough job to plough the whole internet finding resources and programs created by others, in a way, praying that someone has really come up with suitable programs and uploads them on the internet.

Speaking of the file extension, u gave me the idea to add ".jar" to the document name before saving it and it works.

Thanks for your efforts in pushing great reforms to our sch system as I feel it's still lacking on the IT fronts.
