Hi Dek, I am using Google Chrome version 40.0.2214.111 (64-bit) and I use a MacBook Pro. I will go ahead and disable all the plugins except the jKreativ and start from there to see if that is the problem, I will keep you posted on the result.
As for the customization, I am refering that there is a possibility that I will have to build a website for a client and they would require certain customizations from how the jKretiv is right now. In essence it will be the jKreativ but with some changes and API integrations. Is this something that could be possible through you? Let me know if I made myself clear and need to explain in more detail.
