Hi Ludek,
I am Loading the report as you mentioned before. The reason for the extreme clean up is a few versions back of crystal reports, there was a memory leak issue that was causing my application to blow in size.
I believe this memory leak issue has been resolved. so I will implement your version of the clean up and see how things go.
Because it is intermittent I cannot tell you when I can confirm if your solution works for a couple of days.
