Has anyone had problems with their MBP and SanDisk Cruzer Titanium USB thumb drives? The plastic inside the connector is thicker than my Lexar and refuses to insert. I had the same issue with my SR MBP, and now have a Penryn-based MBP with the same problem. I called SanDisk about it and they said it should work but then hung up on me after I explained to them that it won't.
