I have been using your products for years.  Currently I am using Designer Pro X.   I have a web site I created that each time I make a major change on the site & publish it, the owner of the site (or anyone who been on the site recently) has to clear browsing data & then refresh each page because the page displays very strangely.  The font is sometimes very large and the page sometimes shows double content and a few other things.  I have noticed this more often with the later versions of the product.  He is very frustrated with me.  Is there something I can do to remedy this issue?
