Hi I am still in the process of upgrading all our Galaxy servers to the current changeset ("b258de1e6cea", Nov. 18) and now I am running into troubles with the visualization: Depending on the location of my mouse, the filter bar and the other extra buttons jump between two positions, which makes it impossible to use, see Screenshot_1.png and Screenshot_2.png I was looking for relevant code changes, which were committed after Nov. 18. I found changeset "856aac70b018" ("Trackster: refactor action icon creation and initialization" from Nov. 23) for ~/static/scripts/trackster.js Adding this change fixes the problem somehow, but I lose the original icons (for 'set display mode', 'Hide/Show track content', etc) and the bar is now below the track, see Screenshot_3.png Just using the ~/static/scripts/trackster.js from 'central' doesn't solve the problem either. Are there any extra steps I can do in addition to changeset "856aac70b018" in order to solve this problem (except for waiting/using for the next release) Thank you very much for your help Hans
