Is there any tool or key-in to Reload Libraries?

MicroStation CE 14

Hi.

When I open MicroStation, appears a windows loading libraries before opening a drawing completely.

Due to we can add/remove DGNLIB files (or paths in the MS_DGNLIBLIST variable), do we have to close and open MS again? or we can Reload Libraries from the same session?

Also, When I open a file (ReadOnly mode) I don´t know why MS has to load libraries if the user can do nothing...  It does not make more sense not loading libraries when a readOnly file is open?
