CRM 2013 - Navigation Issues

Hello All,

Seems there are some problems in CRM 2013 navigations. I have couple of scenarios mentioned following. Let me know if anyone have any solution/alternate for same.

1) Issue in New Button:- Open CRM and go to sales -> opportunity tab. Click on New button and create new opportunity by inserting all required information. After that, go to opportunity products from navigation menu and click on new button to insert new opportunity product. After that, without inserting any data, click on "Opportunities" in navigation menu which will redirect you to opportunity list view. Now again click on New button to add new opportunity. It will redirect you to opportunity product screen which was previously opened instead of new opportunity screen.

2) We have enabled relationships between opportunity and orders, so user can see Order option in navigation panel in opportunity screen. Now if I open any existing opportunity, navigate to orders and open any existing order. After opening an order if I do cancel that order, I do not have any option to navigate back to project screen except back button or from navigation menu, need to open recent project. Is this by design?
