I just upgraded from 5.59 to 6.21 build 1534 (both 64 bit) yesterday. I keep encountering a problem when I hit the reload button: The setting of a 30 to 0 day range doesn't "stick" and keeps getting changed to 0 to the number of days since January 1, 1970. For example, at the moment it says from 0 days old to 15329 days old. If I don't notice this and hit OK or the enter key, Newsbin Pro tries to load a ton of old headers. It seems like some actions I take between reloads (searching, sorting, filtering, downloading, etc.) is messing this up.
My Display Age in settings in 30. Incidentally, I would love to have an option for a single-click reload which just uses this number and doesn't present a dialog. It would save me a ton of extra clicks.
