Not sure this is a 100% solution, but it works for me:

Track aglSwapBuffers with a global Boolean

Boolean gSwapBufferTracker=0;

...

draw page

aglSwapBuffers(context);
gSwapBufferTracker ^= 1;

...

When you want to display a dialog, simply check gSwapBufferTracker, if 1,
you'll need to aglSwapBuffers to return to the original front buffer.
