I have not tried the beta version yet but the latest Lion Killer I had to remove as my wife acquired a Blackberry Tour (please so remarks) and the current FinderPop pref pane was preventing the installer from working. Installer crashed after I was required to enter my country or region. So, I removed it and loaded the Blackberry Desktop software and will now see if the current beta of FinderPOP will work along side the software.
If not I would rather have FinderPop instead of THe Blackberry software but that will be my battle to fight. Any feedback? I am running Lion 10.1.7 on an Intel iMac.
