2-2.    Activating GTX Graphics Lab 
When activating the GTX Graphics Lab, from [All Programs] in the Start menu, select the "GTX Graphics Lab" of 
"Brother GT-3 Tools" or "Brother GTX-4 Tools". 
<TIPS> 
  For Macintosh, select [Finder] > [Applications] > "GTX Graphics Lab.app". 
 
To load a layout file, activate the GTX Graphics Lab first, then select the file to be loaded by clicking on [New/Open] > 
[Open…]. 
Although it is possible to activate the GTX Graphics Lab when double-clicking a GTPL file, such file cannot be read out 
even if it is correlated to OS.
