This problem occurs with V0.3 beta 9 and 10 for Android ARM, MR3040 or USB connection, Galaxy S3 smartphone or Galaxy Tab PRO.
Camera: Canon EOS 5D Mark II
I enter the Focus Stacking mode and set the parameters (Direction: Closest, Frame Count -5- and Step -Small- unchanged, Start point: Current, End Point: FP1).
When done, I press the Capture button, then Focus Stacking and Continuous Capture are both initiated as you can see on the underneath screen capture.
Continuous Capture seems to have priority since capturing endlessly goes on until I stop it by pressing the Continuous Capture Stop button. Then Continuous Capture stops and Focus Stacking too after one more shot (I decided to stop after having taken more pictures than the Frame Count of 5).
