ShowMessageDialog

[Mikoz]

The cross in ShowMessageDialog's box is weird. I understand that it's not supposed to work when the user must make a choice in dialog, but it doesn't work even when there is no choice(or no buttons at all).
Example in the wiki uses a single OK button for a simple message, but it's different from how similar in-game messages work, like the message from Tech Artifact.
It would be nice if the cross worked with less than two buttons in the dialog.
