I was casting Primal Command in Strixhaven sealed limited on PC, I choose to gain 7 and tutor for a creature. While searching my library I realized I wanted to check my sideboard for lessons, I "minimized" the library search browser, clicked my library and selected view sideboard; I checked my sideboard cards, then minimized that browser and couldn't navigate back to the original library tutor browser. In trying to get back I opened the library browser again, such that eventually I had to click "done" in 2 library browsers, then finally the original search popped up, I could tell because it was just the creatures highlighted but I couldn't select one, I clicked around trying to select a creature: and then time ran out on my turn.
