Hello! Please let me know what is your operating system.
I assuming that your OS is Windows. When you use the text tool for first time Synfig will freeze for a few minutes because it creates a font cache for your system. Just wait until the application start responding again (you will see a text layer appeared on workarea when this happens).
When you will use Text Tool next time there is no delay should happen.
