Opera, Ubuntu and ATS

Right I currently use the Opera Browser (version 8.54) on the Ubuntu OS and have a strange but not unique issues (not unique as in this happens occasionally on other sites). While I sit here typing this the CPU monitor is showing me that slowly the processors usage is going up. This happens whenever i am posting a reply or starting a new thread. If i where to leave the computer to make a cup of tea while on this same page i would get back to find my computer slow to the point where it is impossible to do anything that dosent take a half hour. Does any one else have this problem? Does anyone know what this is, and maybe how to solve it?

Well any way its no big deal, i usually just type what i want to say in gedit and cut paste it over but i thought i'd let you guys know as it maybe something particular in the coding of the page and perhaps something you could take into consideration for the next version of ATS.

I'm not sure this is the appropriate forum so please move if necessary
