>> A workspace is a directory where IGV saves imported graphs  as _graphs.xml_ and  opened graph tabs to _state.igv_. A workspace is loaded when IGV is opened. The current workspace is saved when IGV is closed or when the workspace is changed to a different directory. When changing a directory the state of the new workspace is loaded.

You are right. There was a small mistake in the igv.sh script. It should work now
