[The Geek]

hmmm... Have you done any modifications to the template? (just checking )
Can you put this in the first line of your GEEK_POSTBIT_ARTICLE template:
<-- the firstpostid: $thread[firstpostid] -->
(just above <!-- post #$post[postid] --> )

It is failing that test on the articles you have linked to and hence the reson why it thinks its a comment instead of the article. I have moved some articles about on my site and havent had a problem.
Are any of these threads split by chance?

Thanks for your concern regading the solvents
However, the amount of harmful vapour in a busy salonis about 100-200 times below safety thresholds meaning you are in a much more dangerous arena driving to the plant store to get a new one
Sadly, some solvents simply smell really strong in very low (and very safe) concentrations. However I may just go and get a new plant anyway
