Thanks to Ashley.
It really works.
After I hide the start page, everything goes well.
I tried this software for about 4 days. And I found this software is really very potential. For I used yoyogames game maker for several years and I found construct2 is more user-friendly. However, it seems that the reference books are still in lack. Hope that we can have more detailed reference books.
Anyway, this software is excellent. Thanks for your hard-working.
