Hi Michael,

First i want to thank you for that great, wonderfull, amazing, extremly easy-to-use, hardly to believe it is for free, did i say "great"?, application!
Everthing was going great till i came up with that boolean-bug.
In case you want my file for bug-hunting: http://rapidshare.com/files/8334564/strange_boolean.3dm.html
hope this helps ;-)

cheers,
