Seems I found a severe bug in DPMILD32: it deadlocks when a reloc section in not "readable" :-( Above very-high-quality code should trigger a "missing import" complaint, instead, it deadlocks itself at black screen with white rat arrow - reacting to mouse movements, but not to CTL-C, CTL-BEAK, APPZ/CRASH/MENU, ... -> reboot unavoidable :-( Uncommenting the "readable" or deleting complete section makes the bug vanish. Windaube, OTOH, seems to consider the section (all sections ?) unconditionally as readable.

IMHO the "readable" flag is crap - what's the point of a non-readable section ? Just ignore it and assume all readable ;-)

BTW, any plans to delete NE support from DPMILD32 ? Docs already flag it as "obsolete" , "no advantages" ... etc. - the time has come to kick it out :hungry:
