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 ;-)
