@kcs123 Yes I too lose the entire toolbar. So annoying, lol! As far as the "toolbar-settings.dat" file, I have tweaked it, deleted it, ect. I am truly stumped! I am very well versed on removing residual files left behind. I take "snapshots" of the file structure before adding mods to help prevent such file trash from being left behind when removing a addon or mod! Most every time I add or remove a mod or addon, I do so with a fresh clean instal of KSP. This also helps to clean out and residual file that I may have missed. I try to be very careful to keep things neat and clean when modding. Thank You so very much for the quick responce! It is without a doubt, that all help is much appreciated!
