Morgano: As far as I understand it (and I could well be wrong, but here goes)...

Poser uses a "cross-platform" core. This is so that it can work on both Windows (PC) and Unix (Mac). Unfortunately, because of the different ways these two operating systems work, this can result in some undesirable side-effects. One of those side-effects seems to be (in Windows) that when you click on a menu item (or something similar), unless you are very quick to release the mouse button the click also gets transmitted to the underlying window (the main Poser interface). Which can often result in something you don't want getting selected. Other (similar) effects also happen.

Hope that explains why the problem happens, but if there's a work-around to stop it it happening, I for one, would be very happy to hear of it :bigggrin:

Until then, I'll just have to go on re-selecting the bit I do want to work on (in Windows)..

Cheers,
Diolma
