I have a strange problem with Ultima Underworld and DOSBox 0.74-3: if I run the game twice and quit, it will freeze on exit the second time.
Tried changing core/CPU/cycles/music card/EMS/XMS etc. but nothing changes the fact the game will freeze on quit the second time.
Other users can confirm?

Repro steps:

1. run UW.exe
2. continue a previous game
3. quit to DOS

After I repeat this 2 times it freezes on quit at DOS prompt. A known bug of the original game?
