Hello. I have had this problem for a week now. Trying to Google my way to an answer. Searching for posts and on forums for this huge problem, I have.
By default, you can draw the edges of the preview window to increase or decrease its size. However, I have done something (not sure what) to make it extremely small.
I cannot seem to figure out how to return it to the default size. I cannot see the video this small. I have tried to find and delete the file that saves these settings, and wholly delete and reinstall both the latest build, but older as well. Does not fix my problem. And I have not been able to find a solution on my own. Any help is highly appreciated.
