Graham,
I wanted to close the loop (no pun intended) on my previous problem.
It seems that if I remove the line: osInitialize(); from my indicator
file, the problem of the disappearing/re-appearing plot is solved. I
am speculating that the Osaka plug-in did not like getting re-
initilaized each time the indicator formula was executed. It works
very nicely now. Anyway, I wanted to pass this on to you and the rest
who offered to help...
best regards,
Tom
