The 70-strong Personal Computer Association has heard a Microsoft representative tell them that it is illegal to import MS software from outside the UK.
That follows several cases where David Gregory, head of Microsoft UK's anti-piracy unit, has confiscated software from dealers in a bid to prevent piracy.
But dealers claim a legal test case is needed to decide whether Microsoft is acting legally in confiscating goods legitimately imported from zones within the European Union (EU), or even further abroad.
Gregory said at the poorly attended PCA meeting, held after the Computer Trade Show at the Birmingham NEC, that any breaches of the law would be prosecuted.
He added that, if copies were imported from Europe, the UK copyright law applied.That remains to be tested in court.
