There was an issue with the earlier build of iBlog version 1.4.5 when custom Google Adsense code is used. This is fixed now. Please download the 1.4.5 update again from http://www.lifli.com/Products/iBlog/download.htm or the above download links. This is only for users who downloaded iBlog 1.4.5 before June 29th, 2003.
This issue is caused by line breaks in the Google Adsense code and Javascript functions in CommonLib.js file generated by iBlog. If you downloaded iBlog on or after June 29th, it should work fine.
