Description of problem:
On clean BRMS installation, after I log in I land in Home perspective seeing "What's new" help dialog. I browser through all perspective to dismiss the help dialog and everything looks OK (Project Explorer in Project Authoring perspective, File Explorer in Administration). However when I return to Home perspective and then start switching to other perspectives I don't see Project Explorer in Authoring and File Explorer in Administration.

I observed that when perspectives work the URL fragment ID changes after switching to the perspective (e.g. http://localhost:8080/business-central/org.kie.workbench.drools.KIEDroolsWebapp/KIEDroolsWebapp.html?#org.kie.guvnor.explorer in Project Authoring). When they stop working, the fragment doesn't update corectly (e.g. it remains #org.kie.workbench.common.screens.home.client.HomePresenter after navigating from Home to Authoring. I can see Explore, New Item, Tools, Repository in the secondary menu, but no Project Explorer).

Version-Release number of selected component (if applicable):
ER5, Internet Explorer 10

How reproducible:
-

Steps to Reproduce:
See description.

Actual results:
Project Explorer is missing in Projec Authoring perspective and File Explorer is missing in Administration.

Expected results:
Project Explorer should always open after switching to Project Authoring, File Explorer should open in Administration.
