Remembering settings on second monitor

What TLB version was before update? Also what is your windows version.

Also please can you check if the file setup.ini changed when you press OK in the tlb settings? setup.ini is located in the toolbar folder, you can open it in notepad and find the skin path. When you change the skin this path must be changed too.

Also try to change the skin and then refresh the toolbar. Are the changes saved?
