Opening a large number of forms (above about 15) in the Project Editor will consume all of the PC's User Resources. You may check the amount of free resources by looking in the Help About menu item in the Windows program manager. This will have the effect of not allowing any more forms to be opened or any other applications to be run. If you try running an application nothing will happen. 

The only solution is to close some, or all, of the open forms in the Project Editor.
