Hello,
Sorry to hear you are having issues. Yes, if I remember correctly, this is known issue, where the press state on Standard mouse don't show up. I have checked again, and it does not show. To be sure, I have forwarded your problem/question to Stardock Support Team for their assistance. Please keep an eye on this thread for any updates. We appreciate your feedback and patience.
Thanks
Basj,
