With the new dialog windows of the SP1 I have disabled the option that make the file "save as" when you click upon. Now all the times I try to download a .zip file my IE open directly the file in a temp dir without open the dialog windows "Where do you wont to save this file....". I dont wont to save the file with the right-click mouse>save file as... all the times. If you know where this options can be turned back, please help me. Thank you ( and sorry for the stupid question ).
