Online help is rendering different font sizes when viewed in IE/Chrome.
Any idea what could be causing this?
One of the first things I'd check for would be to see if both browsers are set for the same zoom level. For each browser, press Ctrl+0 and see if anything changes.
Note that the keypress is Ctrl+ (zero).
... and after that, check in the source that a style has been applied so
that the content is not being rendered by the browser's css.
Is this resolved now?
If not, try the previous advice and temporarily switch to a different CSS. The appearance may differ from what you want but likely will be the same in both browsers.
