au3recorder not recording mouse actions under VMware player

Hello

I'm using a virtual machine installed with windows XP SP3 ( and last updates , dotnet 4 ) for installation test purpose.

I tried to use au3recorder, everything works well during recording, but when I stop recording, I just get nothing regarding mouse action.

using  scite 6/10/2012 and autoit v3.3.8.1

For example,
- If I just record mouse clic to bring notepad window in front, nothing is recorded.
- if I input some text in notepad window, I will get something like

_WinWaitActivate("Sans titre - Bloc-notes","")
Send("{SHIFTDOWN}xxxx{SHIFTUP}")

Any idea ?
