Recently, this happens suddenly without any warning, when im inside a window and pressing my arrow keys to move and browse between files in that specific window it won't work.
Instead, it minimizes and maximizes the window, but im NOT using the "windows" key in combination with arrow keys (the keyboard shortcut for maximizing and minimizing windows), and still it minimizes and maximizes that window. So I can't brows my files with arrow keys.
Please help. How can this problem can be solved ?
