I suggest using Report an Issue to report this as a possible Bug. That report should be seen by one of the FileMaker personnel that monitor that section of this forum.
Thanks philmodJunk. As your advice i tried to find report the issue but could not find any option. Then i clicked the the action link in this page and then clicked to REPORT ABUSE. I dont know is that right way to report. Kindly let me know if wrong or right. Thnx
Report abuse is not the correct method.
Look at the file tabs that are at the top of this screen. One Reads "Report an Issue". Click it and then click the link to post a new Issue Report. You'll get a form to fill out collecting information about your operating system and FileMaker version among other things.
