when I try to open a .txt file, there is no suggestion to open it with different applications. There must be a list of apps, including Cool Reader, which can open a .txt file. Such a list does not pop up. The file opens straihgt away with Microsoft Word. What can be done?

Is there a way to lock the settings when you change them? Nearly every time I turn the page while using this app, the settings accidentally change, ie. the margins change, the font changes, the line spacing changes, etc., and it's very aggravating. How can I lock in the settings once I'm changed them to what I want?
