Ah. Hmm my problem was specific to office 365's word program. I hd no other issues with the font. That does sound like a graphics issue with your browser, and the parameters which are set for it.
No he has no problems, he is using Windows 8.x - IE10+11 under 8.x has greyscale blurred rendering which looks fuzzy when text is small or blurred when text is big, but it never looks good as no cleartype rgb is available ( as was under vista/7 ) . The
very same illness that word 13 and all modern apps suffers from.There are thread on this board where people discuss IE11s issue in the same manner like this thread here leads nobody to nowhere..
People why don't you simply see that all complaining is useless. There is no bugs to workaround, it is by design intentionally. Office 13 and W8.x are made that way. Nothing you can do about it and MS will also not do something. They had time since 2012 but
it does not happen. And Win10 / Office16 will be no better. Go figure, register for the Beta Program and install them, you find the same and worser issues.
