Thanks for the reply Vikas. Here are a few of the problem pages. All the type on the left of each image should be set as regular type, not bold.
Home page, which is ok: http://sokovox.com/index.html
A few of the problem pages are below
I tested this on my Windows 7 machine and seems to be a text rendering issue on browser/monitor.
I played around with the Clear Text setting of my monitor and that seemed to have an effect on that. Turning it off shows the text as thin and crisp. Turning it on would make it darker and anti-aliased, looking bold.
Definitely not something in Muse. Would vary from machine to machine and thus user to user, you dont' have much control over that behavior.
Hope that clarifies the cause.
Thanks for the response. I'm not sure what you mean by "browser/monitor" but the rest makes sense that it's not a Muse issue. I'll play around a bit more as now my site looks correct on my Macbook laptop using Firefox 13.0.1 but incorrect using Firefox 13.0.1 on my Mac Pro. So this tells me its an issue on that particular setup. Feel free to respond to my brower/monitor thought. Otherwise, consider this post closed.
