VS 2008/BIDS Hanging with SSIS Project - Constantly Trying to Read Missing Registy Key "CTF \ KnownClasses"

Hi

This is not the first time that this has happened. This is the first time that it has happened where I haven't saved my work.

I'm working in Visual Studio 2008 / BIDS and it has hung. It pegs one core of my CPU at 100% utilization. Process Monitor says that it's trying to read the registry key "HKLM\SOFTWARE\Wow6432Node\Microsoft\CTF\KnownClasses"

I tried creating this key, but then it tried to read the value from "HKLM\SOFTWARE\Wow6432Node\Microsoft\CTF\KnownClasses\F3 Server 38390000"

I created this value as a String with the value of blank ("") However, it now just continues to read this value in what seems to me to be an endless loop.

This is a related question, but appears to have been brushed aside and was not answered: VS 2008/BIDS Hanging Problem with SSIS project

According to "Visual Studio Answers -> Unexpected error encountered. -> Answer 6" the CTF keys "are related to the Vista or Office Language Bar (keyboard, pen, voice recognition settings)"

I'm running:

• Windows 7x64 Ultimate
• Office Professional Plus 2010 Version 14.0.6112.5000 (64 bit)
• Visual Studio Team System 2008 Database Edition Version 9.0.30729.4462 QFE
• Visual Studio 2010 Ultimate Version 10.0.40219.1 SP1Rel
  
• Microsoft Visual Studio Premium 2012 Version 11.0.50727.1 RTMREL

My questions are:

1. BIDS is currently running. How do I break out of this loop so I can save my work?
2. What causes this loop?
3. How can I prevent it?
4. What does this registry key do?
5. What values are supposed to be in HKLM\SOFTWARE\Wow6432Node\Microsoft\CTF\KnownClasses?

Thank you!
