When I installed v3.6 along with the existing v3.1 some of it's components didn't work properly. So I assume I would have to delete my studio.xnf file and start over with just v3.6. This means I would also have to redo the configuration data for all my other modern skins and I don't want to do that.
Anyway I saw that the v3.6 context menu for the coverflow component added 2 new commands, including a "Go To Current Track" command (which would deal with my stated issue). But the v3.1 "Window Dimension (in pixels)" context menu command, which I find useful for making the images larger or smaller, is removed in v3.6.
Bottom line, PeterK does provide an easy way for me to sync the largest coverflow image with the selected song in v3.6, but doesn't add much else that would encourage me to upgrade. Losing an easy way to scale the coverflow images is also a disincentive. So I will stay with v3.1 for now and simply select the next or previous song and back again when the album art gets out of sync with the selected song. This work-a-round only takes 2 mouse clicks, the same number of clicks as selecting the "Go To Current Track" context menu command.
