title: file upload limit in window 8
body: <p>i have a simple file upload code, the code works prety good on window xp and i test to upload the greater than 100kb, but in window 8 i use the same code and i am only be able to upload the maximum of 60kb file,
  What is the reason, is there any bugs on window 8? or there is any other possible problem which cause to limit the uploading file.
  i also try the code on another system which has window 8.1 installed but i find the same issue...
  <strong>Note:</strong> it's not about the php.ini nor about the code, it's all about the logical error, so how can i solve it?
  When i try to upload a file which size is greater then 60kb then the browser stuck on loading.</p>
