Kari, > I would regard vDosPlus XyWrite as a mature solution, and DOSBox-X > as a work in progress. This is a fair assessment. I've been paying close attention to DOSBox-X ever since the "core=dynamic" and "cycles=max" settings made it significantly faster. As you know, I run XyWrite 4 with U2, and I've been impressed with DOSBox-X's compatibility with that setup: virtually every routine, including the ones that depend on AutoIt, run as expected. (In addition to the settings mentioned above, it's essential to set "startquiet=true" and "nocachedir=true"; also, "high intensity blinking=false" is recommended.) As excellent as vDosPlus is, it's at a developmental dead end, while DOSBox-X is in the throes of active development, which can be both exciting and frustrating. But having Wengier on the team gives XyWriters an energetic, responsive advocate within the project. It will remain on my radar, for sure. -- Carl Distefano cld@xxxxxxxxxx
