Dmitry,

I've not got any direct experience with SFQuery. Anyway, have you checked set( "classlib" ) right before going into the SF Query code to make sure your classlib is still in there at that time? I'd be a bit suprised if Doug's code was not using additive everywhere, but bugs happen *g*.

Other than that you can check using set( "classlib" ) to see if your classlib is in the path. If it's not add it back at button.click() time.

>I thought so too but it had to be somewhere in Doug Hennig's code. But since he does not support his SFQuery any more, I have nobody to turn to.
