How do I select a column block of text?

To select in a box, use the mouse to select while pressing the ALT key, or press SHIFT + CTRL + F8.

Where can I download Microsoft Global IME?

Global IME is not necessary because other language IMEs can be added from the Control Panel (Start menu > Settings > Control Panel > Date, Time, Language and Regional Options).

The paste command doesn’t work.

Please check anti-virus software. Sometimes, anti-virus programs block applications to access the Clipboard, and in that case, you will have to explicitly exclude EmEditor from blocking the Clipboard access.
