Two problems:
1. EE 9 does not restore the window position. Tried with beta 29 and 33, WinXP SP3 Pro. I open EE, maximize it, go to Customize -> Window, check Restore Window Position, press the Save Current Window Position button, close EE. Then I double-click a TXT file -> EE opens again with non-maximized window.
2. When I start EE, its window has black corners on the top. After the window size/position is changed, they disappear. I recorded a video:
• Video/EXE (player/codec included)
• Video/AVI (needs MSU Screen Capture Lossless Codec)
