group strangeness

[Klaus Major]

Hi folks,

can someone eventually shed some light on this strange thing?
(I often noticed some kind of strangeness with groups, especially with 
nested groups...)


I have 640 images (80*60 pixel max., 5 in a row) in a scrollable group 
"bilder"...

Now when i use this script to "initialize" all of them, the images move 
to something
like -71,-8156 or so...? :-(

Totally out of order/misplaced and thus completely useless...

I even added the lines with the loc to remember and set again 
correctly, no way!!!

on mouseUp
   lock screen
   repeat with i = 1 to the num of images of grp "bilder"
      put the loc of img i of grp "bilder" into altloc  ## !!
     set the showborder of img i of grp "bilder" to false
     set the dateiname of img i of grp "bilder" to empty
      hide img i of grp "bilder"
      set the loc of img i of grp "bilder" to altloc  ##!!
   end repeat
   unlock screen
end mouseUp

I tried several times and finally found that the line
-> hide img i of grp "bilder"
is the "evil prince"!!!

No problems without this line...


So how can simply hiding an image offset it so far away from its 
original loc???
Is it a bug?

Thanks for listening :-)


Addendum!!!
Some more test showed that there are NO problems when using:

   repeat with i = the num of images of grp "bilder" DOWN TO 1 ###!!! ???
      ...
      hide img i of grp "bilder"
     ...
   end repeat

??????????? Geeeeeez!!!!
To me it looks like the "repeat-loop" is actually SCROLLING the group to
reach the "lower" images???? (Probably not, i know ;-)
