Sergey,

Thanks for your answer.

Please test this to see where the problem is.
Activate the tasklistManager
Generate a program named "Main.prg " containing:

CLEAR ALL
WAIT WIND " This program does not begin it is launched for the second time."
DO (_ TASKLIST)
* - - End of program

Launch DO main.prg again , and the tasllistManager is actived but the program does not Go !
In the file xsource.zip have to be the solution of the problem?
One cannot have of starting program named "Main.prg " ?
I have named my 'Main.prg' To 'Amline.prg' and all is correct Now ... !

Bug?
