Hi, i'm having problem when i try to save my progect..when i click on save button appear this error message "you have to close all dialog boxes before saving", but there are not dialog boxes open..i tryed to reinstall, but nothing..
have any1 got any solution?

Are you sure there is not a dialog box from one of the items hiding behind the other windows. TO check go to the top bar select View - Open WIndows (that will bring a box up that shows all of the open dialog windows -- if there are any listed then highlight one and select the Bring selection to front box (this will bring the dialog box to the front of the other windows so it can be seen -- Close it and you should be able to save ( since these boxes do not update until they are closed the CK will not save your esp while they are open because some changed things may not get saved causing problems later so instead it errors out and tells you that you need to close all of the windows.

There is already a thread here:

As JDFan said above, you definitely have a panel open. The only windows that should be open when you save the CK is the three you start with - Cell View, Render Window, Object view.

Please use the above linked thread for this discussion. No need to two. Thanks!
