Hi, I'm running your Lua test code here, using the main.cpp program. I pressed 5 times the Done button, it worked ok. The dialog is closed every time. The I run again and closed the dialog in the system close button X. It closed ok too. I alternate between Done and Close, ok too. I uncomment the destroy after MainLoop, ok too. Sorry I couldn't reproduce your problem here. I tested using Lua 5.1.
