OK, it took me a while, but I (kind of) found the culprit. So you're right, it was a slideshow issue. I played around with the sizes of the slideshow, and the widgets came back, but then when I put the slideshow back to the original size, the widgets were still there, so I discovered it wasn't a size issue after all.
So, I currently have 10 blog posts showing on my home page. Three of the posts have slideshows. I traced the problem to one particular slideshow. The slideshow code for all the slideshows is generated by Photoshelter, where I have another website (
http://archive.ireneabdouphotography.com). I just go into my Photoshelter account, choose a photo gallery, and tell it to generate the code for a slideshow, and then I cut and paste that into my Wordpress blog post.
So I don't know quite enough about code, but it appears to me that the code that Photoshelter is generating today is different from the code that it's generated at other times. (Though I don't really understand this, because the slideshow that's having the problem was generated earlier than the slideshows that are OK. But when I generate a new slideshow code today, it makes the widgets disappear.)
Here's a slideshow code that works (i.e. widgets act normally):
<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="800" height="600" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"><param name="wmode" value="opaque" /><param name="allowScriptAccess" value="always" /><param name="allowFullScreen" value="true" /><param name="bgColor" value="#AAAAAA" /><param name="flashvars" value="target=_self&f_l=t&f_fscr=t&f_t b=t&f_bb=t&f_bbl=f&f_fss=f&f_2up=t &f_crp=t&f_wm=t&f_s2f=t&f_emb=t&am p;f_cap=t&f_sln=t&imgT=casc&cred=iptc& amp;trans=xfade&f_link=t&f_smooth=f&f_ mtrx=t&tbs=5000&f_ap=t&f_up=f&btyp e=old&bcolor=%23CCCCCC" /><param name="src" value="http://www.photoshelter.com/swf/CSlideShow.swf?feedSRC=http%3A//archive.ireneabdouphotography.com/gallery/Africa-Dreamed/G0000fh1JUCygHXY%3Ffeed%3Djson" /><param name="bgcolor" value="#AAAAAA" /><param name="allowfullscreen" value="true" /><embed type="application/x-shockwave-flash" width="800" height="600" src="http://www.photoshelter.com/swf/CSlideShow.swf?feedSRC=http%3A//archive.ireneabdouphotography.com/gallery/Africa-Dreamed/G0000fh1JUCygHXY%3Ffeed%3Djson" flashvars="target=_self&f_l=t&f_fscr=t& ;f_tb=t&f_bb=t&f_bbl=f&f_fss=f&f_2 up=t&f_crp=t&f_wm=t&f_s2f=t&f_emb= t&f_cap=t&f_sln=t&imgT=casc&cred=i ptc&trans=xfade&f_link=t&f_smooth=f&am p;f_mtrx=t&tbs=5000&f_ap=t&f_up=f& btype=old&bcolor=%23CCCCCC" bgcolor="#AAAAAA" allowfullscreen="true" allowscriptaccess="always" wmode="opaque"></embed></object>
And here's a slideshow code that doesn't work (i.e. widgets disappear):

So the one that works appears to be Macromedia Flash, and the one that doesn't work is I don't Shockwave Flash? I don't know enough about this to know if they're really different...
