The one you sent me looks like it all ran successfully. Are you asking me to explain why your system interacts with ACP in a varying way, and to explain what the tracing means? ImageReady is logged if at that moment it is or isn't. If it happens go from false to to true right after that, the loop terminates without logging ImageReady so the last one that's logged is False. Why is that important or not? How did the tracing get turned on? Did you turn it on? What am I doing here? Does this AcquireSupport solve the camera sequencing hangs in your system? I did make the programmer's comments section corrected to 10 seconds and committed it to the master.
