occasional runaway control - anyone else seeing this?

[Mark Schonewille]

Hi Dave,

One reason why this may happen is the Geometry manager.

Another reason is the margins of the group. If the margins are set to 0 
and you're using the GM or have a resizing script somewhere, the 
controls often tend to "walk".

Also, if you're using rect, top, left, bottom, right and other location 
properties in your script, these properties may change, triggering a 
resizing handler again, which eventually makes the control walk. You can 
avoid this by putting all location properties into variables before 
setting any position, e.g.

put the topleft of grp "This Group" into myTL
set the topleft of btn 1 to (item 1 of myTL + 5),(item 2 of myTL + 5)
-- etc.

If you give a little more info about what you're doing exactly, we might 
solve this problem.
