Re: [perl-win32-gui-hackers] Success with flicker-free windows!

[Steve P. <st...@ba...>]

Hi,

I tried this, it doesnt solve my particular problem at all, in fact it
doesn't make the slightest difference. My window has a *lot* of widgets
(it's a whole application made in The GUI Loft with several panes), so the
flicker is probably very noticeable for me. Also, if you have a flatscreen
monitor (LCD) the flicker is much less noticeable.
