I think so. It's not you that's blocking, it's TeraDesk. Pressing the mouse button will force it to draw the rubberband. Before it does this, it will issue - according to GEM rules - a wind_update(BEGIN_UPDATE) AES call to gain exclusive control of the desktop. After that, there will be no (AES) task switching anymore until the corresponding wind_update(END_UPDATE) call will be issued from the desktop. |
