I'm running 7.8 (64 Bit) Pro - Engine version 1120100 & with the last update I've ended up with a light theme & logging has enabled itself, I've tried enabling & disabling logging to no avail & not sure what's happened to the dark theme :o - Not major issues by any means, but I've looked through the setting & can't find how to go to dark theme & to remove logging. Only a minor problem & thanks for a great product ... Paul :)
Click on view (top left). At the bottom of menu, look to see if theme is locked or unlocked. If locked, unlock it, then click somewhere in the graph to change theme to dark.
Thanks for that :D Sorted.
Thanks chris365
