Strange acts

I m experiancing some strange appearences on my blog (www.dehog.tk), the blog wass fine before I applied WP 2.0, infact it worked fine even after that, but for the past few days something odd has started to happen, the text on the main page of the blog is rather big, specially on the sidebar, then when you jump to singled pages, like say permalinks, it’s fine… I thought it was the corrupted CSS, so I checked the CSS and re-uploaded it, but nothign happened, so then I apply a new custom theme, but the same thing happens, now I though my browser (firefox) has gone insane, and I test the stuff on I.E (yuck) too, but the same thing happens here too, I then test it one of my other computer, using both the browsers, and the same thing, then I recheck from 5 different computers from my office, but I keep getting the same thing…
someone else with the same problem? or if any help is available…I would appreciate that…

thanks and regards
