Firefox 4.0 is my default browser, and I am receiving a script error message when I try to view online images in Family Tree Maker 2011, a genealogy program. Have not had problems until Firefox 4.0. Can't seem to find a setting in Firefox to fix this.

Error is as follows: Line: 63 Char: 4344 Error: Unable to get value of the property 'offsetHeight': object is null or undefined Code: 0 URL: http://yui.yahooapis.com/combo?2.8.0/build/yuiloader-dom- event/yuiloader-dom-event.js&2.8.0/build/dragdrop/dragdrop- min.js&2.8.0/build/stylesheet/stylesheet- Do you want to continue running scripts on this page?

I think that might be an Internet Explorer scripting error, since it is unlikely that Family Tree Maker uses Firefox. I could be mistaken, but if you temporarily (or permanently, if you wish) disable scripting error popups in Internet Explorer, do they go away?

In IE's Internet Options (from Tools menu or the Windows Control Panel):

Advanced tab > Browsing category > uncheck Display a notification about every script error

Thank you very much for your quick reply. I tried to do as you suggested, but the option "Display a notification about every script error" was already unchecked in IE9.

I didn't realize that Family Tree Maker wouldn't use Firefox given it is the default browser.

Thanks, Robert

Applications will use the default browser to launch links externally, that is, in Firefox itself, but most applications are not designed to use Firefox "inside" so to speak. If you make IE your default browser temporarily, does it solve the problem?

I see. Well, I just tried to make IE my default browser, but it did not solve the problem. I receive the same script error when I view the image. (I may not have explained this thoroughly enough at first - I do get to view the image after answering the error message, but the print button embedded in the window doesn't work. Before, I never had a problem with viewing or printing.)

I imagine that at this point I will either need to communicate this to the IE people, or possibly revert to an older version of IE.
