trouble with the reduced view of the project tree

[automatix]

Hello!

In ZS there is a very usefull function "Open in New Window" (right click on a folder/project -> Open in New Window). Now I have a problem with it:

Usually when I opened a project in a new window, at the end of the day I closed this window first -- and then the main window. By opening the ZS again the main tree appeared. OK. Some time ago I opened a project in a new window and then closed the main window first. Since that time the ZS showed by opening the project tree instead of the top level of the PHPexplorer.

Today I've deleted this project. Now the PHP explorer is empty! NOTHING is displayed!

Does someone have an idea, how to make the ZS work correctly again?
