CSS bug | User being lowered on hover

[Inked_Mono]

I've been trying to fix this, but for the life of me have no idea what could be going wrong. When you're logged in, next to the "welcome, " message, if you hover over the username it fills the color in and drops it onto a new area. Examples;

Does anybody know what might be causing this?

Fixed!

In order to fix the issue, I searched for ".toplinks ul.isuser li.welcomelink a" within the style managers, bringing me to "vbulletin-chrome.css". I copied the following from there;

.toplinks ul.isuser li.welcomelink a {
	display:inline;
	float: none;
	clear: none;
	margin-{vb:stylevar left}: 0;
}

And pasted the following beneath it;

.toplinks ul.isuser li.welcomelink a:hover {
	display:inline;
	float: none;
	clear: none;
	margin-{vb:stylevar left}: 0;
}
