I reported the same problem in thread #584882. At that time it seemed that recompiling the report solved the problem, but that was an illusion.

My reports are fairly complex too. I noticed that when the exe runs with vfp6 runtime (-DVFP6r.dll) the problem does not exist (even though it was compiled with vfp7).

It only surfaces with version 7 dlls.

Hope they get it fixed soon...
