I've upgraded on PC 1 (Windows 10) and finally had a "reset" of toolbars like a fresh installation - but personal toolbars are there - I only had to enable them.
After upgrading on PC 2 (Windows 7) (same original toolbars + layout + prefs) - but there was no change after upgrade - I'd my personal toolbars after the first start. During the installation process I didn't receive any question like "if I want to replace Explorer by DO", etc. ... on PC 1 I've been asked.
Is there any difference I've overseen when this happens?
No - I didn't have time for Opera 12 beta tests. PC 1 + 2 was 11.19.
I did a fresh installation of DO 12 on a fresh installed clean Windows 10 laptop. (PC 3). Perfect.
PC 1 (Windows 10) has shown me the default toolbars of DO 12 (like PC 3). Status line was the my defined status bar. All other prefs are there. I enabled my toolbars and all ok. I also have the new DO 12 icons.
PC 2 (Windows 7) still has "my" toolbars - no changes (however - ok after an upgrade - as it should be I think?). But I still have DO 11 icons! Why not the DO 12 icons?
