[DUG] graphics stops updating

[Ben Taylor]

hi,

this indicates you are updating your ui from outside the main thread, which is not
allowed as the vcl is not threadsafe. it is unlikely to be a bug in your audio
components.

you need to implement a threadsafe mechanism to update your ui, possibly using
critical sections or thread.synchronize.

sorry, i don't have time to show an example right now.. maybe someone else has a
block of code to show?

hope that helps,
b
