A few questions: Can you check whether or not modifying /usr/share/applications/hildon/browser.desktop is actually required? (I'm hoping to avoid having to replace or modify another file.) Does passing -o instead of -t to dsmetool work for launching MicroB? (The description of -t suggests that it could reset the device if the invocation of the browser fails...) Does the "browser" process remain in memory after the last window is closed when MicroB is launched using dsmetool? Does it continue to answer the D-Bus methods for com.nokia.osso_browser (e.g. clicking on links in other applications brings up a MicroB window)? Thanks!
