Tool freezing

By default, every SNiFF+ tool is reusable. Whenever a tool is needed, SNiFF+ tries to use an open tool of the type requested to avoid cluttering the screen.
You can, however, freeze any SNiFF+ tool by selecting the Frozen check box in the tool's status line. SNiFF+ cannot then reuse the tool to comply with a new request, and has to open a new tool. This can be useful when you want to compare results. To see this:

Select the Frozen check box in the open Project Editor.
Choose Tools > Project Editor.
A new Project Editor is opened, leaving your frozen one untouched. Checkmark different projects in the new Project Editor and compare the File Lists.
Close the new Project Editor and clear the Frozen check box in the open Project Editor.
