Please report possible bugs.

In DOS64 version I can see test.bat wirh a note: "try run NDN in V86 mode with DarkDebugger32" - did you managed to switch NDN to 64b mode from v86 and back? Or is it possible only via dark debugger?

Yes, this is only possible with DD32 installed as it uses a mapping of all memory below 4GB and has no double mapping issues. The 32-bit version of NDN also works in V86 mode with Dark Debugger 32 installed.

OK, my tests show a problem with DOS32 version under WinXP NTVDM - it displays start-up message and crashes while previous version 00006 works fine under NTVDM...

Graphical mouse cursor was enabled by default (this is incompatible). Now is OFF;
