Several suggestions are made to improve the review of images.
Erratic performance of the browser can be caused by memory and
disk caching features. Network transfer of images can also cause
uneven progression through images. Use the buttons and
to try and tune input for
the maximum your system configuration can handle.
Use the button if your
system seems to fall behind in the image updates. Slow machines may
not finish entire images if the requested update rate is too fast;
watch for incomplete image updates.
If your browser hangs and fails to refresh/load an image, consider reloading the HTML page. Combine this with changing the frame speed, as necessary.
Clicking on a specific time while automatic time-stepping is running will immediately move to the selected time and continue from there.
Note that some actions may take a while to register, particularly when you are pushing your browser to the limits of its capabilities. Be somewhat patient when making button selections. The "slower", "faster", and "stop" buttons are designed to briefly change color when a selection is actually registered by the running code.
