i had this Problem that i don't anderstand at this time.

i use datepicker in many programs and never had this Problem.

In this example and program i use datepicker. First time calling this Programm there is no Problem, may be the second time or third time or fourth time.

I have search many hours on this Errors and have integrated a simple solution.

The datepicker program is generated with Dialog System.

On the Entry ProgramID & "OnDestroyed" USING anEvent, i can see that after calling the program more times, the object reference of aDictionary has no value.

To solve this Problem, i have add in the Entry "C" & ProgramID USING EntryPoint-Data a new line at beginning: set 1stTimeThru to true and now i can run the program a many times without Problem.

Who anderstand this Problem and had a better solution? i have join files

Thanks for help!
