Hi
I agree with kitzuser, and would suggest that you realise the many different variations of systems/setups, which any number of reasons could cause the issue, which is why it has to be repeatable or reproducible, in order to resolve
Our 5.7.1 is working fine, no issues and I suspect the number of users with this issue is low, based on the number of reported users with this issue, but of course it could be that users with this issue has not reported as such.
It would be more helpful if, when users report the issue, they state their OS, exactly how they did the upgrade, any AV running etc... Which should help narrow the search to reproduce the issue
I know I moderate on a commercial forum, which is used world wide, and most when reporting issues, do not include any useful information to help, so it's magic ball time
@roseway, your upgrade works fine on our computer and thanks for the software, your efforts are appreciated
Many thanks
John
