I hope someone can throw some light on this problem before it drives me insane. For some reason, and not after the installation of any new software or updates, I cannot switch applications anymore. When I use CMD Tab it shows my active applications, but where I normally keep pressing cmd tab to cycle through them to select one, it is flashing through them without any input from me as such a speed that you can't choose one. It's like the keys are being pressed repeatedly as fast as the computer can do it. If I use expose (or is it spaces?) to show the windows I have open I cannot click on one to select it using the mouse. I initially thought that I had a problem with the keyboard, but it still failed with mouse only, and normal use of the keys is not affected.
I restarted the computer and opened text edit to see how it switched between two apps, but this is the same.
I also have a problem in Firefox, where I cannot choose an item in a drop down select list, and if I add a bookmark it flashes the dialogue box up for a split second and then it disappears, adding the bookmark as if an "ok" button is pressed immediately. It's OK in Safari and Chrome. There are other applications that are a bit glitchy when trying to select text using the mouse.
It is like there is a constant keystroke happening which interferes with certain functions, but I am lost. Any ideas? Thanks
