Ditto in spades
One thing I have just tried differently today after the usual was to exit Razer Synapse altogether + Razer's Game Manager Service 3 service.
Lo and behold Links fired up first time after having 6 fails at starting. However had to re-eneable Razer Synapse as the mouse settings were unplayable at RTS. So selected my Golf Profile (that I use for Perfect Golf and Links 2003) instead of the VP4 I had been using, then exited Synapse as per previous paragraph before firing Links 2003 up again. Started again very quickly (1st or second time) and the swing was controllable again at RTS.
So do you use a Razer Mouse? I also have a ROG Gladius (Asus mouse) that I may try on Friday (instead of my usual Razer Deathadder) to see if it was just a fluke
