A BOX message indicates that the program called MessageBox() or MessageBoxEx(). If you are using MessageBox() calls as part of your debug output, this provides a convenient way to show where these messages occur among other messages that appear in the Error View.
BOX messages are normally hidden by Purify's default error filters. To display the messages:
1. Select an Error View.
2. Open the Filter Manager dialog box.
3. Select View > Global Filters.
4. Select the Purify Default Filters group and deselect the BOX filter.
5. Click OK.
