Your help (F1) doesn't call up Google Chrome.

When pressing F1 within the latest eM Client 5, the help appears in either IE 7 or Maxthon (which is installed) but not in google chrome which is the default system browser. I am using xp home sp3. When Chrome is the default, EM Client 5 opens Maxthon. Typing the url for help in the xp run dialogue box brings up chrome.

Can you please make sure that Chrome has all its defaults? What happens when you set IE as default browser?

same with any browser,

Does it work for other links? I mean when you click on a link or web address in a mail.
