Running multiple apps from one button

Using 'DOPUS PORTABLE'
I made a button to launch 2 apps off my USB. The first app starts ok, but the second app only runs after I close the first app. I even tried switch the order - same result. Strange.

{alias|homeroot}AutoHotkey_Portable\AutoHotkeyU64.exe  {alias|homeroot}AutoHotkey_Portable\AutoHotkey.ahk 
/homeroot\__SOFTWARE__\StrokesPlus.net_Portable\StrokesPlus.net.exe 

I've been trying to solve this for a month. No joy!

Any advice /comments appreciated.

Add @async: to the front of the command line.
