I had this happen to me once.

I had to Restart and it came back.

Dont think its cased by Track View: Options > Click Behavior > Left Click Locks Scroll.
I have that turned off
I seem to be having a lot of graphic issues with PRV.

Velocity control lines vanishing when moving the mouse along them

Ends of notes vanishing when moving the mouse to the right along them. Will go back to normal when going left with the mouse.

When editing notes now time line can look broken.

I had the now time marker stuck around measure 1, no amount of starting and stopping play or clicking anywhere would get it to track the audio.  I shut SONAR down and restarted and have not seen it or been able to duplicate it since.

for me, grabbing the bar at the top to show/hide the track overview inspector brings it back.

Hope this is going to be fixed in the next patch, as its getting really annoying. Having to restart X2 to bring the the now time line back!
 
Not sure why this topic is marked as solved? where is the fix/solution then?

This only happened to me once a while back. I wounder if it's just another graphics card conflict like so many glitches seem to be.

Can anyone reproduce steps as mentioned in post #10 ?

If you're at Win 7, do indicate if your running Win 7 Aero or not.

Thanks!

I too have had this happen a number of times...

Being in the middle of work I had no time to try discovering why.... I simply saved my project, closed and re-opened Sonar and the project and the now time marker was back...

I've checked all the system options mentioned in this thread and all is as it should be.... but the play cursor disappears at what seem (at this moment) to be random times...

YES! Post 10 steps render the line and marker invisible on my system too.
 
I seldom play with the windows that way so it's not usually an issue for me. However, it is a bug that should be fixed.
 
Any resizing of the windows will bring back the line as will re-docking the floating view so it does appear to be a graphics issue.

Did I miss something?

I see that the subject line has [solved] added but I have not seen a post telling me what is going on...

Can someone point me to what I missed?

Thanks...

@Steve, thanks for confirming the issue. I have submitted the problem report.

@Keni, the original OP problem was solved. But some of us experienced random Now Time missing. I discovered a way to make Now Time missing (due to one of my X1 project was saved with the Console window on top), but not sure if it's related to the OP.
