Problem: I noticed if you have really large strings in the crystal report, instead of having them as type text (aka memo in Crystal) the report won’t ever stop loading. For instance, a field called question that’s string(8000) instead of type text.
Solution: What you can do is cast the string as a text in the SQL before it’s pulled into Crystal. That seems to fix the problem. Something along the lines of:
mysql> SELECT (CAST question AS TEXT) FROM quiz_questions WHERE qid = 1
