You can check on our forum and see the same. There is no way to stop it, this is wpForo design. Long titles will add line-breaks and damage layout/style.

Please only read the last two posts.

Sorry they did not appear straight away.  Ok I understand that this is how it is designed.   

Perhaps this is something that can be thought about, especially on the name of the poster - it is not very good to truncate peoples name !!

Thanks for your help this evening 

One more question on this please.   If you look at the first forum and click to view all topics, then look at the second topic, I dont understand why the first two posts by Janey Hu... are wrapping round onto a second line at 8 characters along, but the post by Brian Wee... is not wrapping until 16 characters.
