Hi, there is the security issue that "Dialogs must be user-initiated." in Silverlight (see question 1355078). There is "a timer in silverlight" and a "UserInitated" flag that is used to do the check (see silverlight forums). That's why you should not set break points before code involved in the procedure.
The problem now is, if SL is running slow, there might be over a second delay at some point in the whole procedure. Is there any way to check if the app is in a valid status to open the OpenFileDialog, i.e. can I read this flag? Is there any there other workaround?
Thx, Juve
