Just in case anyone notices those rounded corners on the forms in this and other video's, it has to do with a new default feature for the new Windows 11 operating system. Not knowing that was driving me crazy so I'm just throwing that out there to save others from asking that particular question.
Upgrade to Windows 11 and you get those rounded corners on all your apps by default. There are windows API's to make that happen if your not on Windows 11 yet.
