Thanks Mathias. Build 148 installed.
Is it my imagination or is the time position at the top left of the timeline now even harder to read. I cannot recall it being black against dark grey previously? It says 00.00.10.15 in this screengrab but is very difficult to make out.
Update - mystery solved. Right click on the box and select Text Colour which on changing from Default to Custom is very readable. You can also change the background. Click on Custom and you can select any colour you like. I'm sure I never touched this in the previous build so updating must have reset it different to previously.
Now if we could only change the pesky black icon colour in the same way............
