I have the Deathstalker V2 PRO Tenkeyless with the saving setting to disable ilumination when idle for some minutes to conserve batery. Everything worked great on Synapse 3 but I recently upgrade to Synapse 4 and imported my profile and now 90% of the time when it goes idle and comes back, the ilumination won't come back. Once the problem starts it won't return until I restart the computer.
My Cobra PRO mouse has the same setup and works fine.
Anyone had the same problem or have any idea how to fix it?
