Can you send me any error messages as you see them, or post them to this topic to avoid other people reporting the same issues.
I know that many issues with kiwitrees and 7.1 are quite easy to fix. But some of these changes will make it difficult to also remain compatible with 5.3, 5.4 so I might have to remove code that tries to retain those comparabilities. Possibly time to set 5.6 as minimum.
(Note, 7.1 does have a number of changes not in 7.0. I have finished testing 7.0 and will confirm the next release is 7.0 compatible.)
