My Chrome browser recently started doing this. When I turn on my computer and open Chrome, my tabs from the previous session are there (Which I love). However some do not fill the screen, and are "minimized" but I cannot make bigger. I have to duplicate, and then close the old tab. I attached a pic of what I mean.
