execution not returning from gx_display_create()

Hello,

I'm running the hello world app on the DK-S7G2.  Starting with a working app on the kit's supplied LCD, I have switched to a different 800 x 480 LCD.  Code execution hangs in the macro call to _gxe_display_create().  

I'm at a bit of a loss to figure out why.  When I run the original application on the default LCD compared to running my own application with my LCD, I don't seen any significant difference in the parameters passed to gx_display_create() from within gx_studio_display_configure() in guiapp_specifications.c.

Any suggestions?

Thanks,

Steve
