Many people are replying with attempts to help, even though IMHO the OP is not willing to do a "homework" Steve stated above, neither is willing to put some effort into providing complete description of everything which will be necessary if someone decides to reproduce the OP's problem. Long ago when I was starting to seek help on mail lists, I read someone's writeup on mail list etiquette. One of the first points was: before posting and asking for help you need to do your own troubleshooting and when formulating the problem, reduce your case to the simplest one that gives the example of the problem you can not solve yourself. In general, the advise was to keep in mind that you are soliciting help from busy highly skilled people, and if it is not clear that you did put sufficient effort into solving your problem, you may not receive any response. This whole thread I perceive as example of how generous the Experts on this list are. I hope, this helps the OP to find appropriate general approach to solving his/her problem.
