[Question]in the show tool...

Hi, all?

I've been getting all around the the forums, and have found many questions
about the show tool. But my case seems like not happened to anyone.

As a beginner, after many frustrating hours, I made a success to export my
SimpleShape.dts. But when I tried to load the file into the show tool. Nothing
happened. No shapes, no errors, only black window.
So I tried to load another .dts file, which is given in the demo, into the tool. But no difference!

If anyone experienced the case like mine, would you save me from my
situation?

Thanks in advance,

HongJin
