Hi Josh,
Unfortunately the issue can't be shown with a screenshot, I did however manage to record it happening.
I used notepad with text in it to demonstrate when the button jams the text is being hilighted. I also enabled high contrast mode in windows so the screen/curser can be seen easily.
I removed 8 minutes of video from the middle because that's how long it took for the issue to first happen.
Video is unlisted and can be seen at https://youtu.be/bwZK2UGvzck
Firmware is the latest version but it did happen with the older firmware as well.
