This is a bug in BC5 that causes an off by 1 hour issue for timestamps in certain situations. Our lead developer is working on a fix. Workaround until the fix is released: click the Rules toolbar button, go to the Comparison tab, then check Ignore daylight saving difference (1 hour).

Sorry, filters don't support absolute paths, they're always global (*.xml) or relative to the base folder (.\*.xml).

Open in New View makes the selected folder the base folder. Because your filter is .\bin\*.xml, it's relative to that new base folder.

The filter is relative to the base folder. If the base folder is c:\folder\, then .\bin\*.xml will exclude files matching c:\folder\bin\*.xml. If the base folder is c:\folder\bin\, then .\bin\*.xml will exclude files matching c:\folder\bin\bin\*.xml.
