Hi, This UDF originaly started in this thread, on the latest post you can find rasim's examples and my initial BlockInputEx udf example. But eventualy i improved the UDF and i thought that it would be better to place it here, in Examples forum. This UDF supports few features that built-in BlockInput() function does not. Here is a quick "features list" if you can call it like this : Block seperately mouse or keyboard input. Block specific keyboard/mouse keys/clicks. [+] Not only hex keys are
