Creating widgets used to took quite long time. Fileselection and other
large dialogs have pretty many widgets => took long enough time for
people to notice...

=> most applications create it once and then hide()/show() it...

If you create it with new, you should be able to destroy it with delete too.
But note that you should first hide() it...

I dont have list of them. Many people dont tell me about what they're doing
and might not yet have their apps good enough for first public release...

the linuxmp3 is the only one that I've seen in freshmeat :)

hmm, I'll have to check this out and fix it.
