TopStyle has been discontinued and support is no longer available. The forum is read-only. NOTE: TopStyle was not developed by the makers of CSS HTML Validator.
I expect to buy TopStyle 6. But TopStyle 5x not bad, Almost everything is there. I am using TopStyle past 4 years. My first preference TopStyle, next Visual Studio 2013.
That's really a shame, I have used and loved this program since I bought it at Version 2! IMHO, it has been by far the best editor out there. I will continue to use TS for as long as it will run on my system!
Just a note, apparently the instructions for installing the 108 hotfix has some issues on Windows 10.
