Figured out what the sidebar-display problem was about: my use of a fixed-width font in this post. I could swear that it displayed correctly on Wednesday when I posted it, but I just realized today that it was the cause of the main body being too wide – it needed the space. I’ve shortened the offending text, and things seem to look better now. Refresh your broswer and see if that’s true for you, too.
The funny thing is that this post was about to scroll off the bottom of the page. I’d have come back in tomorrow, hit Refresh, and everything would have been magically restored, had I not come to my senses and figured this out. No wonder tech support people chug Maalox every day.
As for the weird appearance of the Euro symbol where bullet points should have been, Michael left a suggestion for a template tweak that will hopefully work. I’ll know for sure the next time I do a copy and paste from an external source into a post. Thanks, Michael!
If there are any lingering problems, let me know. I appreciate the feedback.
