A DOS programme I use has started to go extremely slowly - like the system is frozen. Have to sit and wait till it will act on the keystrokes. I run it on a notebook under xp prof and a desktop under xp home. The desktop is a new, clear install, after a HD crash, but the notebook is unchanged. The only thing I can think of is that a recent windows update is causing the problem. Has anyone had a similar issue? My windows updates are all up to date and the programme is an accounting package, there is no online aspect. This is driving me crazy, I don't like sitting twiddling my thumbs. Thanks in advance.
