A button that I have been using for well over 6 years without a hitch will not work anymore. Efective today when in estimates and when i press the "create/lookup workorder" button, the screen pops up but no customer information follows the WO. No customer and no line items. This is a pretty old custom screen that has been working for well over 6 years.
Your stock screen works great. I even created a new button from your stock screen to my custom screen and it still does not work. I am really baffled at this issue.
