errors are raised only on the message bar

[Roger25]

Hi,
I don't know why the errors raised are no more displayed in a modal small window, with the possibility to view the stack of the error?
Here is a image:http://postimg.org/image/nubk1z34j/
The error message appears only at the bottom, with no attention error message.
Why? Is there any setting for this?

Thank you.

Can you go to Tools > Preferences > User Interface / Options, press the "DSA Dialogs" button, and check if the following line exists:

ViewStackDump=n

If it exists, remove it and try again.

It worked, thank you!
