Hi Andy.
Sorry that we have not commented on your problem befor now.
I have had a look back through a few of your posts and from my lap top everything looks normal.
Could you better describe what you mean by fragmented or better yet find one of the posts and take a screen dump and post that up so we can see the problem.
Also befor we can even begin to locate the problem, there are the usual questions. What are you viewing the forum on. PC, mac, Ipad? also which operating system you're using.
Windows, OS, etc.
I am almost scared to ask but are you sure that the issue is not with your computer? I am sure if it is a forum problem then there would be many others with the same problem. As it is the only known problem is with the automatic image resizing. An inconvenience we all have to work around until John moves the shop onto another server provider. He can not run the image sizing plug-in as it does weird things to the images in the webshop. Once the forum and shop are again placed on their own serer the problem will be sorted.
Not much help in this reply but if you can describe the problem, get a screen shot, and eventually a link to the post(s) it happens in, it will go a long way in helping to possibly finding the problem.
It might also be better to raise such issues via direct contact to John, myself of one of the other mods via a PM insted of just mentioning it in a post and hoping that one of us see it.
