SWFaddress.getValue() problem

at moment I’m coding the project with deep linking (SWFaddress). Function SWFaddress.setValue() works fine but SWFaddress.getValue() doesn’t… Actually it doesn’t read any string from address bar after full preload, but if I’m adding value with MOUSE_CLICK event and trying to read it with MOUSE_CLICK it reads value of address but it doesn’t in the beginnig (after full content preload). Any ideas woud be appreciated!
