I use a laptop running Windows 10, and the problem started about the same time as the sCode update.
Example: The Rathskeller Inn page, with my mouse hovering over the plain text, showing it in the bottom left corner linking to the sMail page: http://i66.tinypic.com/2hppu9t.jpg or http://i64.tinypic.com/vff2gi.jpg
It's most problematic, actually getting in the way, at the Ruffie Raffle and Rathskeller Inn, as both pages include drop-down menus, which I can't click on, as I get directly sent to the sMail page.
These are the Themes I own and checked, this problem manifesting itself in all without exception: http://i65.tinypic.com/1zcd378.jpg
And this is my CustomCSS, which I haven't touched in years, but just in case I'm including it here too:
.wishlist{border:1px solid }
.floating_item {border:3px solid blue; position:absolute !important; left:5px !important; top:5px !important}
EDIT: it's stopped?!! I don't know what changed? All I did was delete the sMail notifications in my sidebar. Was that really it? I can't believe the solution was so simple. Still not sure why it was happening, but glad it's over all the same. Sorry for wasting your time!
There was an issue after some of the sCode stuff was changed last week or a couple weeks ago or whenever, that sMail alerts sent before the changes had messed up code that caused the whole page to link to the sMail page.
The coding for the alert was fixed, so any alerts sent now shouldn't have this problem. And yeah, deleting the old alert is what fixed it.
