Import and Export X5 Windows 10

I recently purchased a new hard drive and installed Windows 10 (bad decision). After fixing many issues and finally getting everything to work, today I have a new problem that just began. 

I often export my drawings to EPS. They are simple line drawings, no color.  This had been working fine until today. While exporting, I accidentally made the export box go full screen. Now when I export or import, the window jiggles and dances for five minutes before finally stabilizing and allowing me to complete the task. The window will NOT exit full screen. It remains stuck in that position. I believe if I could somehow shrink the window back down again, it would fix this issue. Any ideas?
