I am having a very odd problem with Visual Studio 2010. After using it for a while, the statement completion comes up in what looks like a vertical IME mode. Nothing I type ever gets to the document, hitting esc gets rid of the box, but any typing brings it right back up. Restarting VS fixes it for a while.
I have uninstalled all languages besides english and set my international settings to english. I have even turned off intellisense and statement completion, still get it.
A picture is worth a thousand words:

Think I fixed it, looking at the keyboard settings, a Chinese keyboard was installed and a short cut was defined to switch between languages (left alt+shift), which presumably I was hitting.
Removed all keyboards but english, turned off the shortcut key and rebooted for it to take effect.
Interesting what comes preinstalled…
