Long Delay when Selected Columns in Tables & Views

Recently, I've been experiencing a long delay after modifying the columns to compare for a table. The wait cursor appears for about 30-45 seconds before the "Save" or any other action can be performed. Currently using SQL Data Compare 13.6.1.7928 Professional. Any ideas? Maybe the underlying project schema is corrupt?

  • SQL Data Compare attempts to simplify the mappings configuration each time you make a change.  However, the project file can sometimes get bloated after a large enough number of modifications to the mappings configuration, especially if the same project is reused across significantly different database schemas. 

    If this has happened, it might be worth creating a new project file and setting up your columns to compare again.

    If you're curious, you can take a look at the project file in Notepad and see what is going on under the hood, it's just an XML file although it's not particularly human readable.
