Game Crashing when hitting a New Level

[ruodd]

1.65 patch from this site works fine, 1.7 doesnt.
Also Atari dont have any known issues for this game on there website or available patches.
As per below -
" Downloads & Patches for King's Bounty
There are no downloads or patches for King's Bounty at this time. "

Also I seem to get some gameplay at the moment as I changed these two settings
setf ~in_mem_maps 1
setf ~in_mem_arenas 1
As per the technical support section of the game manual.
Bascially if I save the game prior to hitting a new level or goin through a new area portal and then re-load that save after it crashes, the game then works 50% of the time, sometimes it crashes again.
Cheers
