2 bugs in one: resolution setting gets ignored and crash when opening save at 1024x768

Hello,

I encountered two bugs that I can reproduce on my machine: I open the exe, go to options (without opening the save first), change the resolution/screen size from 1024x768 to 512x384 and back immediately (bug 1: even though the setting is at 1024 the game opens in 512), then when trying to open the game crashes with the error message below (bug 2: error).

Bug 2 doesn't happen when I open the save first and then go to options to change the resolution.

Location in game: Comet Cave (first time)
Game version: 4.2.3b
System: Windows 7 x64 (fully updated)

Love the game so far!
