I am currently playing on a decent laptop without a good video card so I am forced to play at resolution 1024x768. Everything was going pretty decent until I decided to switch input language (Windows key + Space -> Alt + `) to switch between English and Japanese, and between Romaji and Hiragana/Katakana. However, once I switched to Hiragana/Katakana, whenever I try to click on the middle of the screen, I got alt-tab out of the game in spite of the screen still showing the game. Clicking at the game again will return me to it through a 3 second black screen. It doesn't happen again when I turn back to English input, but only Japanese input.

What should I do in this situation?
