Yes I set "top level elements" to "projects"
Here is how it looks when I load my zend studio.
I want it to load so that all my projects are there instead of having to press that up button 20 times...
Find the file below to edit in your favorite text editor: workspace.metadata.plugins\org.eclipse.ui.workbench\workbench.xml
In my case: C:\Users\juliano\Zend\workspaces\DefaultWorkspace.metadata.plugins\org.eclipse.ui.workbench
And find the line:
<input factoryID="org.eclipse.ui.internal.model.ResourceFactory" path="/xxx" type="4"/>
In my case it was:
<input factoryID="org.eclipse.ui.internal.model.ResourceFactory" path="/Electrolux" type="4"/>
and replace it by
<input factoryID="org.eclipse.ui.internal.model.ResourceFactory" path="/" type="8"/>
And again have peace!
