On some threads, each post is underlined by a thick blue line, and on other posts by a thin blue line. Some posts are not underlined at all, and I’ve run across a few posts that are partially underlined (e.g, only half the width of the posting box).
Just asking out of interest if there’s any reason for this, if it’s just an issue that only I’m having, or if the illuminati are trying to tell me something about each post and I haven’t figured out the code yet 
Rest Essured, you are not alone:

xash, you should be put out of your misery for that one. Long day at work?
I thought I answered this one. Sorry.
Thanks for the link Xash. So I’m not the only person wondering about this, huh?
I noticed today that if I open another window in front of a SDMB page (third-sized window, not a fully maximised one), when I clsoe that window, the thread page underneath it has a different underlining. It now has thick blue underlining for the section that was covered by the closed window.
Stranger and stranger
(and the pun made me smile. I’m essured in more ways than one!)
