Hi Thierry,
>> There is a recent build for 1.7.0 on sf.net, which is not linked from our download page, and does not work anyway.
Did you try it ?
It works here and for the couple of testers I sent it to before uploading.
There are actually all builds from 1.4.1 to 1.7.0 on SF. I asked Sev to make them public on scummvm.org.
If there is a regression where it stops working please do a regression and let me know which is the first one which does not work.
Thanks,
-max
