Dynamic Button for Drop Down Menus stopped working

When I click on the dynamic button to populate a dropdown menu on any page, I get "Unexpected Error" on the first click...and then the button stops working altogether until I close and reopen Dreamweaver. If I remove the Wincache file, I can edit a dyanmic dropdown 1 time. When the dropdown is saved, I get the error:

The following JavaScript error(s) occurred:

At line 67 of file "C:\Program Files\Adobe\Adobe Dreamweaver CC 2015\Configuration\Shared\Common\Scripts\GridControlClass.js": this.object has no properties.

After this, it is back to the "Unexpected Error" or "an unnamed file contains an incorrect path."

I have tried uninstalling all extensions and reinstalling the latest versions. I have removed the Win Cache file and I have deleted the configuration file. I believe I am experiencing the same problem as this post: http://www.webassist.com/forums/posts.php?id=36729, so if you have documented that fix, it may help here as well. I appreciate any help. I am out of ideas.

Do you have mySQLi server behaviors installed? Perhaps try reinstalling that one.

If you still have issues, please post a US phone number or Skype contact information here and I'll call to schedule a screen sharing session and help track it down.

Hi Ray, I don't have that extension. Just DataBridge, E-Cart and Design Extender.

That interface throwing the error and file it references are both built by Adobe, but I see that we updated the file with the error specifically in our MySQLi server behaviors, perhaps to account for this issue. I've attached the file so you can try replacing it and see if that fixes the problem.

I replaced the file and restarted DW. When I try to edit a drop down, I get "Unexpected File Format." and then DW stops working and closes. The first few times I opened DW, I received the attached error. If purchasing MYSQLi will be the path of least resistance, that is fine as I intended on purchasing it at some point anyway.

Yes. We replace that UI in MySQLi Server Behaviors, so that would be the best first step. If that doesn't work at least when I call and fix it with you we would be working with our files and not Dreamweaver's.

So far so good with installing MySQLi. No errors to report, but will let you know if I do. Thank you.
