Hi, all.......wonder if anybody has answer to this mystery on my OE. Am using WIN 98 on my Gateway PC, Pent.2 plenty spare memory etc., etc. Everything was fine until suddenly I couldn't send any e-mail longer than about 8K whether as text, attachment, or whatever. Up comes "This pgm has done an illegal op.............etc., etc. Can handle any length msg incoming no problem but nothing over about 8K o/g. Have checked and cancelled the "break up sent msgs" but no effect. Appreciate suggestions. Dick.
