Why aren results appended to existing data in the output window?
The original version of the Sequence Manipulation Suite appended new results to existing data in the output window. This approach caused problems on some platforms, and made printing and saving results difficult. For these reasons existing output data is now replaced when new output data is generated. When I select and copy data in the output window and then close the output window the data cannot be pasted. Depending on the browser type and version you are using, you may need to keep the output window open when copying and pasting data between the output window and other applications.
