keithcurtis said: I can't duplicate this behavior, but it would save a lot of accidental annoyance. When you have a compendium entry open, even if engaged in the VTT window, as long as it has focus, the back and forward buttons control that window instead of the VTT. This is good, but if the Compendium window loses focus, you can accidentally leave your game. If you have a handout in edit mode, this can cause you to lose all changes. On this note, it would be nice to be able to disable the close window command as well. Please post back if you discover what's going on. Mine somehow works the opposite way. When I have a compendium entry open, click a couple links inside to move to other entries, then when I go back one too many times, as in mouse button back when I'm on the first entry, the whole browser goes back to Roll20 homepage. But when I'm have no compendium or character sheet open, or even if I have one open but my mouse cursor is off that sheet and on the map (can't be on the right hand strip where chat is either), and only on the map, the back button is disabled Well if it's not a feature, it should be.
