Since upgrading to Studio One 4.6 the vertical bar showing the current location keeps disappearing. This means I cannot see which part of a track is being played and I also cannot see exactly where I have selected when I attempt to go to a certain location to edit. This can occur in any window which shows a time line. Randomly switching between windows and turns items on and off will sometimes bring the bar back, but it could then randomly disappear at any time! Please help, Studio One is unusable like this.
