Using dual monitors and having problem with resizing window(s) on Win10x64

[whysomad]

Using dual monitors and having issues since I updated my windows10.Basicly the issue is resizing of the WINDOW of application/program,etc.So basicly what's being annoying for me is that my position of app and size/resize I put doesn't "load" if I re-open the program.Giving an example.

Also I'm using an app to help me control the monitors called "Actual Multiple Monitors" for years now (also I maybe used 2,3 version but I'm using a bit older version which I got used to and is more stable).Basicly I had 1803 build until a week ago and had no issues with window resizing or anything of that kind,as soon as I updated my windows completely to 1809 (latest build and latest update-5. may or something) I started having issues such as this. Also happens to my file browser,when I open it I have to RESIZE it and when I close and RE-OPEN IT I have to RESIZE it AGAIN and I never had to do that before and it's frustrating. It is NOT the app since it happens even when it's not running/disabled completely.

Issue: Window doesn't stay the same size like last time I closed it

What should happened: Window stays the same size even after closing and opening it

What actually happens: Window "resets" itself to original size and causes my problems of resizing it over and over again
