- pressing ESC closes character sheet
- fixed unlimited frost arrow exploit
- improved display resolution auto-detection at first launch

- removed check that disables high texture resolution setting 
  when running low on video memory (some graphics drivers 
  seem to report available video memory incorrectly)
- quick save/load

  file manually)

  the config file)
- custom character portraits

  causes the automap to crash

  a marker on the other map page edits them both at the same time

  of the door (only applies to new games, existing save games still 
  have this bug)

  save that can lead to crashes and the end sequence not getting 
  triggered correctly

  some rare circumstances
- bug fix: standing on stairs and turning with the mouse, followed by 
  a turn using q/e keys is buggy

  sometimes (very rarely) flash in a square where a monster has

  manually from the file system (e.g. in Windows explorer) crashes 
  the game
