Mouse problems, RPCEmu 0.9.4 in conjunction with W10

Since upgrading my laptop from Win7 to Win10 (Home edn) I’ve had persistent mouse issues which weren’t in evidence before. The mouse pointer is visible as before and reacts normally to movement, but when I click-select a file or application, the first, and often the second or third, click is ineffective. Sometimes two closely spaced clicks will cause a response, sometimes not. It makes RPCEmu virtually unusable, to be honest. The mouse is a standard, USB 3-button, non-scroll wheel HP item, and worked perfectly well with RPCEmu 0.9.4 and 0.9.3 under Windows 7. It also works normally with W10 natively.
Has anyone else had similar problems, and if so, is there a fix?
EDIT: it makes no difference whether I operate RPCEmu full-screen or in a window.

On the Mac the “Reduce CPU Usage” can cause weirdness similar to that described. IIRC it has been reported that the same can also occur on a Windows host.

I’ve always experienced a bit of mouse click weirdness with RPCEmu, on Windows and Linux hosts. Just have to hold the button down a tad longer than you would normally. [Edit: where ‘always’ here means going back to 2010 or thereabouts, not just this month… Not a winge, just an observation!]

Same issue here with the mouse. Like you say, makes it difficult to use some software. Win 10 PC. Looks like some issue with the last release.

Same issue is seen here now on a new 0.9.4 Windows 10 install. It is impossible to double click anything. There is some intermittency, it can come good briefly. “Reduce CPU Usage” has no effect.

Oddly enough, disabling ‘Reduce CPU Usage’ here caused the pointer to become completely inert; it didn’t react to anything. Restoring ‘Reduce CPU Usage’ and adjusting down the mouse click speed in Windows’ Settings-Mouse-Additional Mouse Options-Mouse Properties-Buttons seems to have some beneficial effect, but doesn’t fix the issue here. I think I’ll try dropping back to 0.9.3 to see if mouse behaviour is any better.

Update: rolling back to 0.9.3 didn’t do any good, so I reinstalled 0.9.4. It turned out that disabling the ‘Reduce CPU Usage’ did restore normal mouse operation, on my system at least, albeit at the cost of a +/- 20 deg. C hike in average core temps, from around 50-55 to 70-75 on the laptop – not ideal, but I’ll accept that if it means RPCEmu functions normally.
