Thank you for purchasing TextQuick. On start up TextQuick needs to load everyone who has a mobile number from your phone book so it can display the list of people. In addition it also needs to read any recently received text messages so it can update the order of the list. To prevent TextQuick from having to scan the inbox completely TextQuick stores some information, including the last order of the list on the C drive on your phone. If your C drive is full TextQuick will not be able to save this information. This will cause problems, as the next time you start the application TextQuick will need to rescan all the messages in your inbox. I would suggest that you ensure that your C drive is not full. To make TextQuick faster you can change a setting in the application. If you set TextQuick to jump to the background after sending a message then TextQuick will continue to run in the background. Next time you want TextQuick it will simply jump to the front of the screen. All of this will happen in a fraction of a second. Check out my web page here : http://mind-flip.com/textquick/using/index.html . This page details how to change this setting, have a look a section titled "Changing Settings". I personally own a Nokia E50, a much less powerful device than the N73 and TextQuick starts up significantly quicker than the built in phone book. In addition I have had feed back from a number of N73 owners all of which have commented on how quick TextQuick is to start up. It's always good to receive feed back and I'd be interested to know if the above tips help to improve your use of TextQuick.
