Summary0001490: Freeze when file dialog tries to display overly long tooltip of file type selector on mixed-DPI screens


When hovering the file type dropdown in the Open File dialog, OpenMPT will simply freeze. Looking at the stack trace, Windows ends up in an infinite loop in its tooltip handling code due to the overly long "All Modules" filter string. The same happens if "Other Formats" is chosen from the dropdown.

TagsNo tags attached.
Has the bug occurred in previous versions?

Only way to workaround this so far seems to deliberately include a shorter (*.x;*.y;*.z) string in each filter.

Worked around in r15587 (trunk) / r15588 (1.29) by shortening the displayed strings.

r15684 identified a few more troublesome dialogs.
