is there a way to 'bulk-change' the path of all custom icons and skin files used in one's custom taskbars?
Unfortunately, the corresponding drive letter, and therefore the path, has changed in my case from D:\[My_Skins&Icons_Path] to E:\[My_Skins&Icons_Path]
All of the toolbars are stored in /dopusdata/Buttons and are editable in a text editor. Simply load the affected toolbars and do a find & replace (d: to e:) in your editor. Restart Opus once complete.
