KeyDown results in alternate characters popup (Mac)  

Using SDL2 Max2D (thanks Ron!), all is going well except for keyboard input.
I am finding that holding down keys which have alternate character options (A, Z, etc.) are always resulting in the alternate character popup, whether in fullscreen or windowed mode.

Is there a preferred method of receiving key input in SDL2 Max2D instead of KeyDown in order to avoid this?

Sure thing and I don't know about this one, it seems to be an ongoing issue with the latest SDL release https://github.com/libsdl-org/SDL/issues/3622

Also technically, KeyDown is part of polled input and not SDL2 related as I don't see any wrapping to SDL's keyboard functions, so perhaps try MaxGUI key events instead like EVENT_KEYDOWN

That link actually pointed to the solution - when using SDL2 and polled input, you just add:

SDL_StopTextInput()

..and If needing full text input capability (with accented characters available), add in (temporarily):

SDL_StartTextInput()

That way, if you want to test some older BlitzMax examples (or touch up some old code), you can do so without a major rewrite of input routines.

Thanks again!

That's great, glad you got this sorted out.
