Ok, I'm no CSS expert...
...but I simply changed my sidebar from the right to the left and it doesn't appear 'wrong' when you go to read comments. The only problem is, I'd prefer my sidebar to be on the right. At this point (getting no real help from LiveJournal, as pasted below), I thought it was interesting and figured I should mention it here in case it might trigger an idea from someone who does know css. ;) I'm about ready to just try another layout if not just for a change, but I'm sure a 'fix' will come in time (from a helpful user, definitely not from LJ) and I still like component (when it's working right, of course). :P
This the code I changed to temporarily 'fix' my sidebar issue (chose 'left' instead of 'right'):
### POSITION OF YOUR DEFAULT SIDEBAR ###
# Right, left or none?
set comp_state = "left";The last contact from LiveJournal regarding my request for help with this issue (that I made on behalf of all users with this problem):"Thank your for your report, and I apologize for the delay in responding to your request. Because of the complexity of your question, it took longer than normal to provide an answer. It appears that your custom theme layer contains code that is no longer compatible with recent changes to the Component layout layer.
Unfortunately, it is simply not possible for LiveJournal developers to test every possible combination of users' customizations for conflicts when making changes. You will need to either edit your current custom theme layer so that its code is compatible with the current Component layout or change to one of the system-provided Component themes, which you can then customize to your liking. You can change to one of the system-provided themes from the "Choose Journal Style" page here [http://www.livejournal.com/customize/].
If you prefer to edit your current theme layer, you can do so from the "Your Styles" page here [http://www.livejournal.com/customize/advanced/styles.bml].
The FAQ linked above provides more information on how to use the Advanced Customization area."
