Every time I open a window, like the documentation, an annoying "Formating notebook contents" dialog appears for about 2 seconds. This didn't happen before, the first thing I did when I made a Windows clean install was install Mathematica 10, and those dialogs only appeared when opening the program for the first time. I tried resolving the issue by myself to no avail. It's really annoying.

The start up is really fast

{
 {"Initializing kernel connections..." -> 0.031},
 {"Initializing cell styles..." -> 0.109},
 {"Initializing fonts..." -> 0.188},
 {"Initializing menus..." -> 0.203},
 {"Initializing defaults notebook..." -> 0.25},
 {"Initializing defaults clipboards..." -> 0.375},
 {"Initializing internal preferences..." -> 0.406},
 {"Initializing kernels..." -> 0.453},
 {"Opening Welcome Screen..." -> 1.703},
 {"Preloading Favorites..." -> 1.719},
 {"Handling CommandLineOptions..." -> 1.719},
 {"Opening Files..." -> 1.719},
 {"Do Startup Action..." -> 1.719},
 {"Closing Splash Screen..." -> 2.344},
 {"Finished" -> 2.344}
}

The only problem is the dialog pooping everytime. Any ideas?
