Cubase pro 8.5/I think I have a problem

I am using Cubase 8 pro (8.5.20), it is awesome but I think I met a small problem.
When I import audio file, the size of temporary window can’t be set up, I want it be bigger but every time when I open it, which only show me as a min size. I ask some of my friends and their Cubase don’t have this mistake.
Can you please help me to solve this problem?
Thank you,

I second that. In versions of Cubase prior to 8.5.20 you could make the Open/Audio Import/etc windows larger and the next time you open them they would be that size. Now that’s not the case - it resets every time. Very annoying.
