Okay this is just silly... I've been messing with the executor demos since like 1.2, and no problems. 1.99k hits my drive and bang, 'not enough conventional memory'. EVERY time. No matter what. No matter whether there is 620k free conventional, or if I get rid of all my TSRs. Makes no difference. It is often accompanied by a EMM386 error which forces a reboot. Anyone else having similar problems? James Moody
