On my custom layouts, I have the "Books & Dictionaries panel" set as a panel in the upper right of my layout. For some reason the little maximizing square on it is missing - and - it seems to be missing on all of my panels. I have tried toggling "enable layout customization" on and off but that doesn't make them reappear. The only way I can maximize a panel is to go to the drop down menu under view and click "maximize book panel", or the name of whatever panel I'm seeking to maximize. When I do that, it maximizes and the little "two" squares appear in the upper right (along with the x). When I then click the two little squares, the panel goes back to the previous size but the little square to maximize it again has vanished. The exception to this is when I choose the "Swordsearcher classic" layout. In that layout the little square is present on each of the panels when they are minimized and I can click it to make them full size without having to resort to the drop down menu. Wanted to see if I could get some help fixing this issue? Version is 8.3.1.74 on Windows 11, 64 bit. Thanks
