I have never seen this behavior. But what I would do is go to settings on browser and clear history, clear cache.
Then I would follow ncinerate's instructions to put some security on your touchpad in the getting started sticky (I coped those instructions below).
If that doesn't work, then you can always doctor your touchpad and start afresh, just leave a few hours for the process.
"While you're at it fixing "security issues", take a second to load up your touchpad web browser and surf to:
Tap on local storage. From there, you can manage your flash player privacy settings. At the -very- least you should use the "only from the sites I visit" setting to help prevent your flash player from assisting websites in tracking your surfing habits. Personally, I just turn the local data storage off. Yeah, it means I might need to adjust my volume next time I'm using youtube but I feel better without flash cookies watching me surf the web.
Last but certainly not least, lets get a proper SSL secure and -encrypted- google search added to keep our queries nice and private.
Open up the touchpad browser once again and surf to:
Pick the touchpad google SSL, wait about 5 seconds, and a little popup will appear at the top of your screen saying "new search engine found". Add the search engine, and then set it as the default search engine for your "just type". You can change this while adding the engine, or if you've went past that just go into your launcher, tap settings, select "just type" and there is a spot there to change your default search engine."
