Admincp Popdown menu's, Ajax etc not working...

[محروم.كوم]

I just re installed my windows 7, so on a fresh windows 7 now, and the ajax doesnt seem to work now (when i click edit in post it goes to new page), and popdown menus in admincp not working.

Also i cant insert smilies the mouse goes over then but does not bring the Hand icon up.

Also double clicking on post titles will not edit it does nothing.

Did i mess something up in my forum perhaps before reinstalling win 7, or is there just a add on my browser is missing??

edit- i just clicked edit on this thread and it automatically edits the post in the same page..what is it???

By the way I am using vB 3.8.4, can a mod move this to the right forum if necessary, i thought i was on 3.7 sorry __DEFINE_LIKE_SHARE__
