Product Cache Issue

Hi ,

For last couple of days we are facing product cache issue in our environment. We have cleared the cache for the products where we are making any change but when ever we are trying to test that change in admininstration product by validating the product or by adding the product in an order and then customizing it then the changes made are working intermittently. Example for a rule create with attribute comparision it's working correctly for Mozilla browser but not working for Chrome browser and vice versa.

Please let us know how this issue can be resolved.
