Maybe there is already a topic about this "problem", but I couldn't find it.

Last week I installed the newest version of SketchUp PRO on my new computer. Normally I could customize the toolbar, but when I drag some tools from the Large Tool Set in de toolbar above they only stay there until I close SketchUp. Every time I open SketchUp I have to drag in the tools again.

Is this a bug which needs to be fixed?
