How could OS2 have fixed the fill issue?

You were all (most of you, at least, with Korg's) furiously denying the problem even existed up until last week or so... now you expect a fix THAT fast...

C'mon guys, get real!

It takes time to work out the fixes, beta test them, incorporate them into a new OS without managing to break something else in the process...

This is why you need to acknowledge and demand action as soon as possible... because even if they get on it right away, there's still a fair amount of lag time in getting it done.

Quit playing 'defender', and start playing 'improver'
