MouseMove event Issue

[DCONSULTING]

Dear all,

I'm starting to develop a bot for magic online.

I have created a very simple script

===================================================================

Logon() ;

Func Logon()

WinActivate("Magic Online v3.0.83.2")

Sleep(5000)

MouseMove(1,1)

Sleep(100)

MouseClick("primary")

EndFunc

=====================================================================

The activation of the magic online windows works but after nothing happen, move do not move...

What i do not understant is that if i change the winActivate target for an another application (notepad or google) it works!!!

Can someone help me with this issue ?

Many thanks by advance.
