The splits won't work for that application then, but it will still work for everything else.

Hope that helps! ]]> https://www.displayfusion.com/Discussions/View/please-fix-your-wm-syscommand-overide/?ID=a76112d7-253b-4032-8ea3-47cdf6f4a061#4 Thu, 20 Jun 2019 18:15:36 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/please-fix-your-wm-syscommand-overide/?ID=a76112d7-253b-4032-8ea3-47cdf6f4a061#4 DisplayFusion I'm not 100% sure actually. I will check in with our devs to find out. ]]> https://www.displayfusion.com/Discussions/View/please-fix-your-wm-syscommand-overide/?ID=a76112d7-253b-4032-8ea3-47cdf6f4a061#3 Wed, 19 Jun 2019 17:14:53 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/please-fix-your-wm-syscommand-overide/?ID=a76112d7-253b-4032-8ea3-47cdf6f4a061#3 DisplayFusion Hello Keith!

Yes I am.
Is there a way to keep the Split feature and have the WndProc fixed?

I'm a developper and I noticed my applications won't receive their WM_SYSCOMMAND WndProc (code &H112).

Especially those with the following m.WParam :
> &HF030 - Maximize
> &HF120 - Restore
> &HF032 - Maximze (from double clic)
> &HF122 - Restore (from double clic)

As soon as I close DisplayFusion, everything works as expected.
Please fix this behaviour, as this is really bad since you won't let any other applications get those very important WindowMessages for themselves.

You probably don't release the MyBase.WndProc(m) once you've used it. I would say you can do this within your own application (overiding a normal behaviour with your own and then blocking the WndProc), but not when it's a general sheel application like displayfusion is... causing others to be blocked!

Thanks a lot,
