Double click bug in "Windows XP" compatibility mode

[TheMurderousCricket 5,046]

Perhaps it is an already known aspect of the game. If not, consider it a discovery or a warning.

It involves, what I refer to as "cycleable MMPs". These are MMPs which you can place in your city and then click on them multiple times. Each click, results in different variation of the first object or in different objects appearing in lieu of the original one.

Now, on to the bug. I ran my game on Windows 8.1 with the Windows XP compatibility mode enabled. When I tried to plop some of my cycleable MMPs in this mode, I noticed that odd instances of cycleables were always skipped. It was as if the game read my single click as two clicks at once.

I don't remember how I ended up in the Win XP compatibility mode in the first place. I probably tried to resolve some other issue this way. The bottom line is you should probably avoid it!

I remember a thread a while back how Windoze 10 really messes up the MMP cycling so this is likely a similar situation.

Someone more familiar might remember the exact solution. Seems like it was Control+Clicking or such that turned out to be a workaround. (Wait for the real experts tho as that's just my guess from memory.)

I believe here it is with the solution @Terring posted: [Link] 

It might be something similar happens on Windows 8.1 also, and so maybe that might help too.

I have heard how running those Compatibility Modes can do more harm than good. At least with getting SC4 to run smoothly (as you're probably aware of), two of the biggest stability improvements are to use the -CPUcount:1 command, along with SC4Fix installed.

This post @rsc204 made a while ago sums up the reasoning:

Honestly, in my testing I came to the conclusion, if your game works without using a Compatibility Mode, it's best not to enable it. If your system is having problems, well then XP SP3 is most ideal for SC4. However, if activating compatibility mode does not improve anything, once more I'd recommend switching it back off again. This is not the magic bullet some people suggest it to be.

 

So unless there happened to be a particular need where it could benefit, it seems like it's best avoiding.

You can hold the Right Mouse Button whilst using the Left Button and it won't skip the stages of the MMP, but frankly this is for me clunky. The issue seems to relate to updates to DirectX, specifically DirectInput, which handles things like Keyboards, Mice and Gamepads. Some update seems to have caused issues with certain legacy functions somewhere. However, by setting up dxWrapper, you can 'convert' the input calls so they are registered as intended. There is no need to use the Wrapper for DirectDraw (Graphics), although many there days probably are using that also. This fixed the issue for me on my test Win10 machines, I'm guessing it would work on Win 8.1 too.
