I was having an issue with this plugin last night. I clicked on the built in nUI button to switch over from Recount to look at the Carbonite map. When I went to go back to Recount, the Carbonite map was stuck over the top of the Recount window. I ended up closing out the Carbonite minimap.
I'm using nUI 5.01.01
Let me know if you need any other information!
