[HKN] Everquest script

Hi all.

i made this script for multibox on everquest:

// ========== HOTKEYNET EQ MULTI-PC SCRIPT ==========
// EverQuest windows must be named EQ1 (SK), EQ2 (shaman), EQ3 (Bard), EQ4 (Mage1), EQ5 (Mage2), EQ6 (druide)

// HOTKEY : NumPad1 - Burst DPS
<Hotkey NumPad1>
<SendPC local>
<SendWin EQ1>
<Key NumPad1> // SK taunt (macro cast taunt, disarm, snare)
<Wait 300>
<SendWin EQ3>
<Key NumPad1> // Bard (cast melody)
<Wait 300>
<SendWin EQ4>
<Key NumPad1> // Mage1 (macro on EQ cast 3 DD)
<Wait 300>
<SendWin EQ5>
<Key NumPad1> // Mage2 (macro on EQ cast 3 DD)
<Wait 300>
<Restore>

// HOTKEY : NumPad2 - simple Heal Shaman (macro on EQ cast 3 heal) + Druid (macro on EQ cast 3 heal)
<Hotkey NumPad2>
<SendPC local>
<SendWin EQ2>
<Key NumPad2> // Macro Heal Shaman
<Wait 500>
<SendPC local>
<SendWin EQ6>
<Key NumPad2> // Macro Heal Druide
<SendPC local>
<Wait 500>
<Restore>

//====Target/follow===
<hotkey Numpad7>
<SendPC local>
<SendWin EQ2>
<Key NumPad7>
<Wait 300>
<SendPC local>
<SendWin EQ3>
<Key NumPad7>
<Wait 300>
<SendPC local>
<SendWin EQ4>
<Key NumPad7>
<SendPC local>
<Wait 300>
<SendWin EQ5>
<Key NumPad7>
<SendPC local>
<Wait 300>
<SendWin EQ6>
<Key NumPad7>
<SendPC local>
<Wait 300>
<Restore>


My problem is that work aleatory ... don't know why.
