I just updated to Desktop Manager version 4.5.0.15 (May 30, 2008) from Desktop Mnager version 4.3.0.17 (Nov 12, 2007). Everything was working fine until I decided to run the Synchronization option to synchronize my Blackberry 7520 with my Dell PC. This process went from running in about 3-4 minutes under Desktop Manager version 4.3.0.17 (Nov 12, 2007) to more than 30 minutes under Desktop Manager version 4.5.0.15 (May 30, 2008). The process that took the longest was my address book, I have over 1500 entries in the book. Has anyone else experienced this issue with the new version?
