Karl, thanks for your quick response.
I tried this on our demo gallery, in static mode(not playing) and can't reproduce the lockup. I think if you click like crazy on a thumbnail while another one is loading or under the transition, you might get some 'white box' effect, but it never locks up ...
Any idea why it happens more in my case? could it be related to the amount of images in the gallery, or the settings of the thumbscroller?
For now, I have set the transition interval from 10, down to 5.
It reduces the chance of the lockup.
It's a pity it does not look as smooth now, but its better than a lock up...
Hope you can solve it in the next update!
regards,
stan
