If you click on a link in a POP3 email ( for example ) Opera will fire up as it should...but at your set home page and not on the site to which the link was relevant.....you then have to go back to the email and click the link a second time to get Opera to go to the site correctly.
The same applies to any other link in any document type.
However, if you click a link in an IMAP mail, Opera will open the site correctly.
Of course, to access an imap mail you will already have your browser open to access your webmail server.
In other words, clicking on a link in a pop3 mail or other document type when your Opera browser is closed......wrong page opens...........click on a imap link, when the browser is open..........page opens correctly.
So, to open correctly a link in a pop3 mail, you must either click-browser opens-go back to mail-click again on link..................or have the browser open before you open your email client...open mail..click on link.
Both these options are a pest and a waste of time.
Small point, I know, but in my wee sideline business of offering genealogical research it can become a right pain and it has been like this for all versions since 10.10.
Opera have been told time after time, their forum is full of members complaining of this...but no remedial action is forthcoming unless I have missed something.
I have asked several time on their forum if the issue has been resolved, but cannot get any confirmation........and I will not update my version until I know the issue is fixed.
