Hello again

Progress has been made on my little drawing program I have implemented a feature that enables you to save your image to the SD card, and right before the program starts saving the image I would like to display a text on the screen, saying something like "Saving image...". The code looks like this:

GRRLIB_Printf(20, 20, tex_font4, BLACK, 1, "SAVING IMAGE...");
GRRLIB_Render();
// Here SD card IO is performed (fatInitDefault, fopen, fwrite and all that stuff)

My problem is that the "Saving image..." text doesn't always show up before the program starts doing the IO. It maybe shows up 1 out of 3 times. I have tried calling VIDEO_WaitVSync() before doing the IO, but it didn't solve the problem. My code is single-threaded.

My question is: What is the proper way to ensure that the screen is updated after the call to Render()?

Thanks a lot in advance.
