--- Comment #36 from Adam Bolte abolte@systemsaviour.com --- Confirming your new patch works fine for me when applied to an otherwise clean 1.7.35. Tested with Warlock - Master of the Arcane in a 64-bit prefix. Without this patch, the game refuses to run.
Note that I still get a Program Error (Unhandled exception) when exiting the program. I guess you would have seen that though so assume is unrelated.
Thanks for keeping at it.
