Tip: you are blocking text selection for the terms of use and in a number of other spots. People often use text selection to copy and paste words for a variety of reasons. Some people select blocks of text to help mark what they are reading, and some people use it to paste the words in a dictionary or translation service of their choice. (Or when making a bug report to copy the version number from the about screen.)

Don't block text selection for prose, only for UI elements.

thanks for the feedback and reporing the bug, the goal was to have the custom context menu instead of the browser one; but seems like that casued an error, will fix it asap.
