For the case when a settings dialog is open for a Sysgen block, when a dialog help button or model info block is clicked and spawns a NEW Firefox browser for the linked HTML document, one may not be able to dismiss the parent dialog, model, or subsystem until the browser is closed. When this problem occurs, it can appear as though Matlab is hung.
The problem does not occur if Firefox is already open when the dialog help button or model info block is clicked.
The workaround is to close the spawned browser first. If a browser was already open before clicking on the Help or Model Info block, this does not appear to occur.
This affects Win64, and Lin32, and Lin64 and will be fixed in ISE version 13.1 software.
