The program is still hanging with the "Please Wait" message showing. Something in your initial code changes causes the program to hang, and export DISPLAY=:0 was not needed. Determining in your first changes that causes the breakage obviates the need to add export DISPLAY=:0 .
Is your new binary not also hanging on your machine ?

On my side it doesn't stop at please wait. I've tried it with the command and from the screen by tapping the green play button to start the program.

That's interesting. Something about the way my machine here is set up is not quite right, then.

I'm at the restaurant and I updated the vt_data file to the new one and I got the "please wait" I reverted the vt_data file back and everything worked fine. I'll do further testing after work.
