I use Chrome version 45.0.2454.85. It's up to date.
I also get on craftster at my work computer which uses Internet Explorer I believe...I don't know the version, I'll have to get back to you on that. Needless to say, I experience the same thing on that computer as well.
Dang. That's the same browser and version I use regularly, too.
It's so hard to troubleshoot when we can't recreate it. Grr, technology!
