I'm sorry to hear that you have problems with our products however we will need a bit more info on all these in order to provide you fix if necessary. Can you reproduce this issue on our examples or you get this only in your project? Can you post more info about your environment? We fixed similar problem recently related to Tablet PC service - can you try to turn this off temporary to make sure if the problem again is related to this or not?
