Dear Ray007.
Hi, Ray007.^^
I appreciate your review on FrameWhite as a BIG difference.
Dear Ray007, would you use FrameWhite Firefox version?^^

I notify you my recent news.
As of now, I do also works as a Microsoft partner developer.
If you want the upgrade version of TimetableForWeb,
Timenote is available in Microsoft Azure Marketplace.
Also, WeekNote provide a pretty note each weekday.

I will do effort to upgrade FrameWhite as Tb change version.

Sungho.
