SNAP bugs are becoming a nightmare, students are losing work, every time students open the costume browser their computers crash or they lose their work. In the latest example, This student's project mysteriously deleted all costumes from all sprites, then wouldn't recover the previously saved version.
Most of the issues involve Chrome 77, but we have no alternative as software is strictly controlled by the district. Is there any way to revert to SNAP v4? Considering how much time is being lost, and in light of the massive lost-work conundrum of 2017, we may have to find another platform.
Thanks for your reply and for looking into this. If you have a chance, would you mind looking at this project and seeing if it's possible to recover it? When I try to open it, I get a "load failed: type error: cannot read property 'attributes' of null" message; this happens in any browser on multiple computers, and it will not allow me to recover previous versions.
Regarding freezes and hangs, I'm afraid we can't do much if you can't update from v77... Snap v4 wouldn't help, either, because the costumes bug is in Chrome, not in Snap!.
I'll try to take a look at recovering this particular project, but again it's very suspicious that every single user that has had this kind of problems was using v77. I understand you can't update Chrome yourself, but can you use Firefox instead just to confirm whether problems still occur there?
I didn't say kids should do it, but CS teachers (who probably know what they are doing) could be trusted to use the portable version. If a district thinks that CS teachers are not to be trusted with choosing software, who they think are then?
Sorry for not making myself clear. School IT people, not teachers, disable USB drives altogether because that's a thing they can do in Windows, but disabling USB drives except for their official ones with an unhacked Chrome isn't a thing they can do.
