In the attached screenshot, you can see the blue box that says "• HTML / HTML5 / XHTML Validator • CSS / CSS3 Validator..." does not word wrap properly when the workaround is not implemented. There should be a lot more text in the blue box but because it doesn't word-wrap it seems to run off to the right off the box and thus becomes invisible.

Here is a page to reproduce the word wrapping bug in IE and in Edge:

If anyone else has any thoughts or comments on Windows 10 and the new Microsoft Edge browser then please post them here.
So far my initial impression is to wait for Microsoft to get more bugs and kinks out before upgrading to Windows 10, unless there is a good reason to upgrade right away.
And on a side note, I was disappointed with Cortana. At first I kept getting a general and useless error message and Cortana wouldn't do anything. When I did finally get Cortana to work I asked it/her to set a simple timer and it/she couldn't even do that... but I do really like the idea of having Cortana in Windows 10. You can hit Windows+C to go into voice recognition mode and ask Cortana something.
