Hi all, I assume this is pretty basic (well.... hopefully!!) I keep getting these messages that pop up in a blue bannered box (like standard windows error) saying "XXXXXX - Application error" Where i have written XXXXXX are various messages that pop up every couple of minutes, like "Taskmgr.exe - application error", "msmsgs.exe - Application error" or "Iexplorer.exe - Applcation error". They are then followed by some text along the lines of: "The instruction at 0x77f58dc5 referenced memory at "0x000077b". The memory could not be read" I have no idea why this happens! Any clues? and also on how to stop it?? I just click on the 'OK' to terminate the program but Iexplorer and messenger etc still seem to run ok... then shortly a new message pops up! Really annoying, any ideas!? Cheers.
