I updated this field but it still has old value.
Confirmation needed.
Please have a look before the new beta version comes out ;D

Oops, sorry for this annoying.
The problem is in class ps_product.php
LINE 465:
'product_s_desc' => vmRequest::getVar('product_desc', '', 'default', '', VMREQUEST_ALLOWHTML),
should be:
'product_s_desc' => vmRequest::getVar('product_s_desc', '', 'default', '', VMREQUEST_ALLOWHTML),
Fixed in Beta 2 (rev 1077)
