there is a reason behind this window: it indicates that the rig is not stored. this might sound obvious to power users but as for the questions asked when the window was not there, it wasn't obvious to many others. we took the chance to add rating for your convenience, this way you don't have to dive into a menu in order to rate a rig. some time ago, it was voiced on this forum that a convenient way to rate rigs would be appealing since rating through the Rig Exchange website is way to complicated and as a result, "nobody" rates rigs.
pretty much every action you take (selecting/editing a stomp etc.) makes the window go away, and if it doesn't, that's an oversight on our end which we will address. the dialog should slow nobody down. we are open to discuss how to improve the window, we can even take it away but you should be aware that with 5000 rigs and counting in Rig Exchange a decent amount of data in regards of the quality of a single rig makes the database much more appealing for everybody.
best, gs
