Hi borate,
I have installed vers. 16.09 and everything now works as aspected. I am very grateful for your help.
I have tried all my project files, loading, viewing, saving, save as, closing down, opening again, editing, changing bin clip thumbs, - everything works fine.
Also the new version is much faster on my machine now, all clips are loaded quick as lightning.
Surprisingly all my VPJ files start with version= 13, also the new ones that I create. But no problem.
The little yellow fx shows up on some of the clips, - not all, even if they are identical.
I came to think of a problem I had in 2023, the vulnerability CVE-2023-23514, but of course this relates only to iMAC operative systems. Caused me some problems at that time, but it is apparently solved by now.
But in summary: I am up and working now again, thanx once more.
Have a nice weekend!
Kind regards Hans
