What steps will reproduce the problem?

prompt screen to complete action using which launcher will appear.
2.
3.

What is the expected output? What do you see instead?
1.Pressing home button each time will return to selected default homescreen 
(ADW selected)like normal, in any running app and task manager.

What version of the product are you using? On what phone? What Android
version?
1.3.3 standalone
Samsung galaxy tab. stock.
FROYO.DXJJ1. Asian.

Please provide any additional information below.

The problem is after eachtime I launch the task manager by short holding the 
home button to clear tasks or multitasking apps, when I re-press the home 
button to go back to the homescreen, the pop up notification to select which 
launcher will appear.

Ive already tick the mark as the default launcher but everytime I launch back 
the task manager the prompt will re-appear.

Using the stock launcher will result the same as well. 

Ive tried uninstalling ADW, launcher pro and homesmack and only leave the stock 
launcher, then it returns normal.

When I reinstall ADW, the problem reappears. Mark it as default launcher again 
still a no go.

Ive been using ADW for nearly a month now on the Galaxy tab without any problem 
until yesterday.

What task manager are you using or do you mean the stock one?
