No, theres no border to grab, and the top bar is off the top. Theres no window menu for some reason (the app is called dolphin btw, but I don't think that should have an affect).
I did find a solution though, if it is a bit complicated. I found the .ini file associated with the application in "~/Library/Application Support". In that file, there was a value called "RenderWindowHeight" that had a negative value. I switched it to positive, and reopened the application. The window was then right in the middle of the screen. This isn't something you'd want to mess with if you don't know what your doing, but it did fix the problem
