Below there is an animated GIF that shows the issue with PB 5.62 x64 (on Windows 10).
Using PB 5.70 beta 1, the situation is even worse because the IDE is written in PB, and PB 5.70 beta 1 has this new bug in ListIconGadgets.
And my settings should not only be there after imediately re-opening that window, but also the next time when I'm launching the IDE. So the widths of the "Configure Tools" window and of its colums should be stored in the IDE preferences.
