MOUSE() Event Strange Behaviour

[Freire]

Well, I'm trying to implement the Long Click Event to some functions on the Virtual Keys
Due to some functions being called over time, I have to call for MOUSE() function instead of WAIT(-1) in order to catch mouse interaction.
While WAIT(-1) successfully gives me back when long clicks occur (Although I already understood the reason why it behaves a bit unusual>
Bug in REPEAT + WAIT(-1) when UNTIL 0;), the MOUSE() function is failing to give it back to me.
From help:

Quote:MOUSE[(index)]
Returns two lists describing the current location of each potential pointer (or empty lists if the pointers are not used). The output is {x , y, original z, original y, type} where type is 0 (for new), 1 (for completed), 2 (for drag), 3 (for stretch), 4 (for rotate), and 5 (for long click).
The optional parameter index is the nth element that would have been returned—x, y, original x, etc.—had the parameter been omitted (or –1 if no pointer activity had occurred).

So I was expecting MOUSE(4) to Return -1,0,1,2,5 for a single finger iteration, but I was not able to reproduce the Return of 5, and apparently I'm receiving 1 only when using the SOFTMENU area.
Also I noticed a MOUSE(4) returning number 7:
Put two fingers, stretch, then release one finger. Not 100% chance, but very high chance of giving number 7 out of MOUSE(4).
Code to test these: [Things that were commented out have also all been tested, give it a try.]
