Ok,fixed,i had to reset all my presets in settings,this just bought me back to the main view page(ie printers)
Looking at the main printer control,at the bottom the camera icon was set to new window,have now set it to embedded overlay
Hope this helps anyone who comes across the same problem

Hi,forgive me,rather new to 3d printing and bambuddy,i started to print and thought i'd look at camera view,then left it there while i went away,now the print has finished,i closed bambuddy,but every time i relaunch it,it doesn't come up with the main view screen it shows cam view from before,tried what i can,but still stuck
I hope you understand
Thanks
