Just in case you missed this the other day, FileMaker 11 Support Ends September 2015. And they have no idea why I can no longer drag and drop in layout mode. Dang it!
Start working with your clients on upgrading to the current version (v13 as I write this):
On December 2, 2014, FileMaker announced that as of September 25, 2015, FileMaker 11 products will no longer be available for direct sales and support including technical support, replacement media, downgrade media, and downgrade license keys.
FileMaker 11 products:
• FileMaker Pro 11
• FileMaker Pro 11 Advanced
• FileMaker Server 11
• FileMaker Server 11 Advanced
FileMaker Pro 11 and FileMaker Pro 11 Advanced are qualifying products for single license upgrades to FileMaker Pro 13 or FileMaker Pro 13 Advanced until September 25, 2015.
Note: FileMaker Go 11 was discontinued on September 30, 2013
