PhAB Crash

I am running 6.21B PE.

In PhAB I highlighted a line in the “Module Tree” adn right clicked on it.

I selected “Print Tree…” on te bottom of the pop-up.

When I clicked on the “Print” botton of the bottom of the printer
selection dialog, PhAB crashed.

There is a 4 MB core file if you want me to upload it.

What can I do to Print a module tree?
