Message repeats too often?

[BuckoA511]

I've been using the Wordpress plugin version of the Fight For the Future code and the author suggested I post here. I'd like to know how many times the campaign message should be shown to one visitor, because it seems inconsistent. Testing my site on Google Chrome, I got the popup appearing every time I browsed to a new page. This is unacceptable to me and will just likely annoy visitors. On IE and Firefox however I only get the message once per site visit, which is absolutely fine.

I don't understand this inconsistency as apparently no cookies are set per-visitor. I'd suggest that showing the message every time a new page is loaded is simply going to frustrate visitors and be unacceptable to webmasters. Although the code can be added to just the homepage, many visitors will enter the site through a search engine link to read an article that interests them and therefore may never touch the homepage.

I suggest adding code so that the message is only displayed once per visit.
