Keyboard locking up when doing some combination.

[jayendra]

This has happened about 7 times so far.

 

I am zooming, splitting zooming etc with cmd, ctrl, alt keys mouse wheel.

Suddenly my keyboard locks - only function keys and cmd,ctrl etc keys work - nothing in the middle!

 

I hear a little locking (key in hole turning maybe?) sound and then all I can do is restart.

 

Q1 - is this a logic thing?

Q2 - is this a macbook thing?

 

I have macbook, leopard, logic pro 8, logitech v470 mouse.

I have no idea what that sound is that you're hearing, but what you're describing suggests that your mouse needs re-charging (it's a cordless mouse, yes?)

 

It could be (maybe, just a guess) an incompatibility between the Logictech mouse driver and OSX. Do you have a special Logic set-up in your Logictech Control Center? (System Prefs pane).

 

When this happens, does the keyboard work in any other applications? (Knowing the answer to this question is KEY).

O wow I have almost found the combination - I was able to turn it off and on and off and on and off.

 

Its something while holding alt/option and then pressing mouse buttons or scroll side.

 

The sound is like a metal tinkle going up - to lock and down in pitch to unlock.

 

anyone ever heard of this?

Found it !

 

double tapping alt key - locks and unlocks keyboard.

Don't feel bad, dude.

 

I've used macs since... Before they were called macs, and I didn't know that.

 

Lucky my keyboard doesn't have an alt key, LOL.
