going nuts again

[MisterX]

Hi everyone,
 
Not long ago, there was a mention of problem with images not refreshing
correctly based on a changing path of the image.
 
Well, not long ago, actually centuries ago (naturally, i couldn't find it
anymore despite being sure i entered it - and i doubt it is easily
replicatable - and i dont have time to rebugzilla it), i posted a problem
with some images not refreshing correctly irrespective of where the image
was.
 
In this case, im using buttons as patterned objects. And since groups can't
be set opaque reliably either on WinXP compared to W2K, again a button for
bg pattern. hummmm... 
 
First observation is that changing a backpattern doesn't always refresh -
sometimes it's just black (try to flip the pattern image horizontally and
see that happens to your buttons' patterns after). 
 
Since these are all cloned objects, often is the case that one or the other
button patterns start to act up on their own despite their properties. Some
display a black 2 pixel border (no border is show though), others don't even
show their patterns or only do so when clicked! In another case, each time i
display this window with patterns, a patterns shows or doesn't... 
 
All images are buffered naturally... Sometime a simple click on the button
will restore the image! WTF?
 
This is a time waste each time it happens. You just can't fix anything on
these buttons. Happens mostly on buttons but on menus too. So you have to
redo one from scratch! 
 
Any ideas or fixes?
 
thanks
