Hello Riz,
I am afraid that the version that you are currently using is relatively old, regarding the release of the browsers, where the problem is faced. Many fixes and enhancements are implemented since the version that you use, in order to address different problematic behaviors, caused by the new browsers.
My suggestion is to upgrade to our latest official release, in order to get advantage of the enhancements and the bug fixes.
Regards,
Nencho
