SuperNova becomes unresponsive after Windows returns from power saving modes.

After returning from sleep, standby or hibernate, SuperNova may become unresponsive or completely freeze.

Dolphin is currently investigating some reports whereby some users may experience one or more of the following symptoms after the computer returns from Sleep, Standby or Hibernate modes:

  • SuperNova runs slowly, the mouse movements may be erratic and difficult to control.
  • The magnification may have frozen / be locked in one position
  • SuperNova is not responding and the Control Panel is greyed out.

Current Workaround

Unfortunately if you are experiencing any of the issues listed above, the only workaround we have found at this current time is to disable Windows power saving modes.

Go to 'Control Panel\Hardware and Sound\Power Options\Edit Plan Settings' and select 'Never' for 'Put the computer to sleep' under On battery and Plugged in.
