--- Comment #1 from Béla Gyebrószki gyebro69@gmail.com --- Better late than never...I've just discovered that the problem goes away if I change 'Cycles' in DosBoxTR.conf from the default 'auto' to anything else, e.g. "cycles=8000". It seems the problems occurs when autodetection is enabled. This is the default DosBox setting with almost every game I encountered so far.
