Windows 10, FileMaker Pro Advanced 15, Database hosted locally on FileMaker Server 15.
I have a script that can cause the "Data Viewer" to go really slow while I am in the script debugger. The script will move to a layout where a relationship is out of context and FileMaker temporarily locks up while trying to update the data viewer.
I get a "Find in progress..." dialogue box pop-up. If I close the data viewer while the "Find in progress..." dialogue box is visible on the screen then FileMaker Pro Advanced will reliably crash when the Find in Progress... dialogue box disappears.
An image of the Find dialogue box in front of the data viewer is attached.
