Microsoft's position on spell check is that it's part of their Office offering. So don't expect a Microsoft update to provide spell check unless you purchase Office.
As to IE 7, if you read the posts in the forums you can get the idea that it's a hit and miss update. Sometimes it works for most but for some it's a struggle to remove it and get back to what worked.
Same story for WMP 11.
At this date I don't advise updating to IE 7 or WMP 11.
I have Windows XP Home with SP2. I use Firefox 2.0 but sometimes IE6.
The thing I like about Firefox is my ability to enlarge the size of the font by holding down Ctrl and using the wheel on my mouse. When using IE6, I can enlarge the font size in some websites and not in others, and I assume that this results from the mechanics of the website rather than from IE6. Also, there are times when using IE6 that the font size is too large and I can't reduce the size. The other thing I like is that when I misspell a word it gets underlined and I can highlight it, right click, get the correct spelling and make the replacement with a mouse click.
What I am wonder is whether I would get those features with IE7?
A main reason I use IE6 is that, using Hotmail, when I updated to Firefox 2.0 I lost my ability to use the Rich format features that I can use in IE6 and that I formerly could use in Firefox 1.5 after installing an Addon that doesn't work in Firefox 2.0. I couldn't find an Addon that would give me that ability in Firefox but I am wondering if I am overlooking one?
So, my questions are:
If I install IE7, will I be able to always enlarge the font size as I can now do with Firefox?
If I install IE7, will it provide me with the same kind of, or maybe one equal to, the spell check I get with Firefox 2.0?
If there an Addon for Firefox 2.0 that will enable me to use Rich Text features when using Hotmail?
