Is it Mage_CatalogInventory_Block_Adminhtml_Form_Field_Minsaleqty? Signature Magento Tech PM -- To avoid trouble, don’t tamper with core code. Write customizations!

I was getting this and others errors(some with Grid.php in Admin > Sales) after I upload my version of magento. I uploaded the Mage folder again( app > code > core > Mage) and everything was working again. Backup the Mage folder before doing this. Regards
