I am currrently updating Domo-Sudoku. The site is now working nicely with Internet Explorer. Unfortunately, there is a bug with Microsoft IE Inner.HTML function which caused so much trouble. As a Mac user, I was not aware of this problem but I got my hand on a PC recently. That was really helpful.
Many visitors also use Safari for PC which is compatible with Domo-Sudoku. This navigator compatibility is a real pain in the neck.
I am on holiday until late August but I will be working on the site from time to time.
