Command Centre thumbnails (rack images) for the past few weeks/months(?) seem to be regenerating/refreshing erratically, with racks of the same specification rendering at different sizes, then those preview sizes changing when "update screenshot preview" is selected. There are other sizing behaviours I can't figure out, but I'm finding it almost impossible to view all my racks at the same size (when they're the same sized racks). This is a relatively new behaviour/bug but I can't say when it started. I'm using both the latest Chrome and Firefox browsers under Win 7 Pro. It seems dependent on how many "columns" of racks are displayed, and the width of the browser window - I'll get one full column of racks that are much larger previews than others. Anyone else getting this? Cheers!
