Summary	0006655: Clicking on the ruler area makes the playhead jump to somewhere earlier in the session
Description	When zoomed in a couple of steps in the timeline, locating the playhead by clicking on the ruler bar makes the playhead jump to somewhere random earlier in the session. When zoomed out it behaves as normal. See video for example. I have the same issue also in MB3 interim release 2257. Ardour 4.4 64-bit (from Ardour.org) Ubuntu 14.04
Additional Information	Here's a video showing the bug: https://www.youtube.com/watch?v=Dqsap_vCKiU Included session folder by request of las.

nick_m 2015-10-29 17:16 reporter ~0017542	I'm having trouble reproducing this. Could you check that all your modifier keys are actually set to something in editor->preferences->user interaction? This would be best done on a nightly build where you can see what the recommended settings are. thanks.

ma120mk11 2015-10-31 09:30 reporter ~0017560	I deleted the ardour4 folder in /home/ove/.config and that solved the issue. I didn't change anything in preferences before this happened. I was working on a session (no bug) and ardour crashed. I reopened the session and then I got this bug. And the bug was present on all sessions, this led me to think it was the ardour config that was corrupted. Deleting the mixbus3 config folder also solved the issue in MB3. I did take a copy of the mixbus3 config folder before I deleted it. I can add the folder as an attached file if you want, maybe you will find what caused the issue. Thanks.

nick_m 2015-11-01 07:45 reporter ~0017566	Thanks a copy of the old config would be good.

ma120mk11 2015-11-22 11:59 reporter ~0017657	I had this bug happen in MB3 again. This time I removed a file at a time from the Mixbus config folder to see where the problem was. The bug went away when I removed the ui_config file. The difference between the old ui_config file and the new one are these: Old ui_config (bug): <Option name="draggable-playhead" value="1"/> <Option name="font-scale" value="105684"/> <Option name="strip-scale" value="1.05"/> <Option name="mixer-element-visibility" value="Input,PhaseInvert,RecMon,SoloIsoLock,Output,Comments"/> New ui_config (bug fixed): <Option name="draggable-playhead" value="0"/> <Option name="font-scale" value="102400"/> <Option name="strip-scale" value="1"/> <Option name="mixer-element-visibility" value="Input,PhaseInvert,RecMon,Output"/>
