In the portable Edition of TeamViewer, I did save my preferences to the TV.ini file and all the settings are saved but there is one major nuisance. Every time I launch TeamViewer portable, I need to accept the EULA message. This wasn't the case in the past.
Please give us the option to save that preference or at least to be able to add a line to the TV.ini to it remembers that the user accepted the EULA and doesn't show the box upon every launch.
