Hi everyone!
I found a fix that works for me on Windows! It doesn't let you resize the window manually, but let's the computer automatically adapt the resolution of the window to your display.
I have a 14 inch laptop with a 2K resolution display and the windows were way to small to be usable. Now they are even a little too big, but after I hide the taskbar to get that little extra space it's perfect!
I've attached screenshots so you can see how it worked for me. Here are the links to the fix

if for some reasons those link do not work, try googling something like "windows rescale high DPI manifest".

Good luck!

Thank-You Bobby,

I haven't had this issue since the later windows 10 updates.

Bobby You know.. I've been playing with the moxf editor app and realized the issue was not yet resolved. I'm using a surface pro 4 with an external monitor. The first link, a YouTube video gives you a lot of spam when trying to download the manifest file I would run from that one. However your second link from Dan Antonielli is very helpful there was a little elbow grease required but my moxf8 app was resized about 2" bigger all the way around. I just wish there was a tweak to make it completely full screen.

For others with the same issue apparently it is a flaw with Microsoft windows DPI Scaling and it affects users who use multiple displays

in short and in non code speak.

Danans fix DanAntonielli fix dpi scaling issues

requires that you go to the registry and paste in a one line sentence I'm assuming this enables a manifest file (Danan explains where to navigate), next close out the registry
Then you copy his manifest file (a text file) to your notepad or text editor.
Then you navigate to the folder where the offending undersized application file is and you paste the text file below the exe file for the program
Then you right click and rename the file to match that of your application. Using the MOXF6_F8 Editor.exe as an example you would simply add your manifest file under it and rename it as MOXF6_F8 Editor.exe.manifest.

Close out and reopen your app you'll see as bigger app! this fix as Danan will mention works with other apps like photoshop cad programs illustrator etc. Hope this helps.
