Re: [Boa Constr] save dialog issues

[Riaan B. <riaan@e.co.za>]

Hi Steven, thanks for helping out,

This is quite and old bug. I've isolated the problem before. It seems
you cannot call modal dialogs while in the click event of a 
GenericButton.

I've now implemented a work around for this by posting an event in the
on click event and then popping up the save as dialog after the on 
click has finished. Works now.
