I am having a problem when using version 2.05.25.0804 of the OpenGL ES 1.1 SDK on Windows, using the libraries directly from an application of my own.
If I do any rendering, then when I shut down my application, then whilst my main window closes, the SDK GUI window which pops up on startup remains visible and the application does not exit. If I then close the floating window, the application still does not exit, and I have to use shift-F5 in the visual studio debugger to stop it.
I have found that there is a workaround, though, if I set the option setting to disable the SDK GUI window on startup, it exits properly.
Is this a problem you are aware of? And are there control functions for the popup window in libgles_cm.dll? I cannot seems to find any documentation that relates to control of the dialog.
