Re: problems with the redraw of widgets and callbacks with long operation time

["Ignacio Nodal" <inodal teleline es>]

Oh, I see... well, then I'll have to be patient and wait for my VRML to end loading. 

The main computation time takes place in functions from the CyberVRML97 library. 
It's not my source, and I don't think I want to modify/hack it hehehe :-)

Thanks for all,

Ignacio Nodal
