max function "showdialog" returned with error 9999: Internal Error
Trying to save an amxd and getting this from ableton . Not sure what to do
go this too, sometimes.
close, open again it is working but it is quite annoying.
It doesn't happen always but here is the process to "get" it:
- create a liveset
- import the default max for live audio fx device (same for all 3 max for live default device)
- open the max for live device
- try to save it... it gives this :

hm... any news about it. have the same problem and no idea how to fix it!?
hm. tried again. I opened a new live - set - saved it with a new name.
then opened the m4l-midi-effect-preset and saved it under a new name - then I started to program and everything worked...
I'm having the same issue on a Mac Book Pro M1 Pro (14 inch 2021) here :/ after getting the error, I'm not even able to load M4L again without restarting the laptop.
