[Icc-mot] RE: Icc-mot Digest, Vol 41, Issue 6

[Richard Man]

Rene, please trim your post. Please send me OFF-LIST a ZIP file of a 
project demonstrating the problem. Make it as small as possible but 
be sure to use all the memory options etc. that cause the problem. 
Send it directly to me and not to the list, and I will take a look at it.

Thanks.
