Yes, thank you. Sorry I don't get back here as often as I should. So, thank you for your response.
When I went back to using Mozilla a day later it was good again.
I just had a problem yesterday, where my internet slowed right down, and I couldn't access royalgames.com, but managed to order seeds from another website. Once I changed to Mozilla the speed improved and I was immediately able to access royalgames.com. Again, not sure what the problem was, although at times it doesn't matter if I use the Retro or the other engine, royalgames will still tell me I cannot access certain games, i.e., word battle. I will check out how it is working right now and see if the problem still exists.
