Comment 5 for bug 1051856

This seems to be a Thunderbird issue (probably the exchange calendar plugin).
The suggested refinement would be to improve overall user experience when the user interacts with pop-ups. It would be highly desirable to add at least "Close" button and "Never ever show again" ("More Info" button would be nice also).
I think it is applicable to all the applications that uses popups.
For now the behavior of certain application is quite annoying when it comes to displaying popup with unclear problem description and suggest no way to fix it.

I know, the unix philosophy tends to minimalism but it also demands not only that each component should have only one responsibility but is should do it well. For now popups seem to clearly lack the possibility to dismiss them (forever!) and provide the user with more information - at least the application that issues certain notification. From my point of view this may be considered as an incompleteness of popup feature that does not improve overall user experience.
