Thanks for your feedback and support! There is a new post in the forums bug section with more potential fixes if you are using dual monitors and still have any issues on startup.

Here are the patch notes (1.0096.4726):

• Fixed an issue with S+ Mighty Weapon "Godbreaker II/III" being invisible
• Fixed an issue with S+ Mace/Shield "Blue moon II/III" being invisible
• Fixed "Summon: Skeleton" animation error
• Fixed Necromancers "Summon: Skeleton" now also work outside combat
• Fixed "Mend Pet" animation error
• Fixed Beastmasters "Mend Pet" now also work outside combat
• Tweaks to total souls needed to open dungeon portals
• Tweaks to shop systems, (new cap for selling maximum 100x "Scrolls" or "Eye of the gods" at a time to prevent coin overflow errors)
• Tweaks to improve multi-monitor compatibility
• Tweaks to current config resolution dialog (to prevent resolution errors causing freezing or crashes
on first time startup with dual monitors)
• Added functionality for "Move to primary display" and "Get Display list detection" by default on startup
• Tweaks to monitor settings auto-saving on exit (These new modifications runs when closing the game on a second monitor / non-primary display in windowed mode to prevent resolution errors on next startup)
