I used to use the various "switchers" for the purpose of going back and forth between ms and tf. I found what worked best for me was to simply uncheck the tf under the options on the today settings list. I disabled the start first feature for ms by using memmaid to keep them from competing at startup. I have no slowness or freezes using this method. I only switch occasionaly so this might not be desirable for everybody, but at least it's solidly stable.
