Well, if you *absolutely* have to do this, then you should: intercept the timer tick have it check if your INT9 handler is in control. if not, rehook INT 9. of course you have to intercept several INT 21H fuctions, and this will cause some horrible crashed (for example if somebody else writes a program that does exactly the same thing, but it can be done... I don't recommend it though........ -frisk
