If I do a count of the children each time, it is the same (5, which at the
place I am checking this is the base amount for the window before adding
it's contents). I have not looked at physical memory, I assumed that was the
issue since it compounds itself on every iteration.
I can not re-use the children, I have no idea what set of children are going
to be in the tool, it is determined by the user at runtime. All I can do is
take the contents from the server and add them to the window when that
window gets used.
I have about 5 different types of windows, that is why I thought simply
removing the children then re-populating the window would work, but in IE it
doesn't work so well. FireFox works just fine.
In IE, if I clear the entire window before loading that tool window by
hitting F5, the window loads fast, So I am going to try completely disposing
the entire window each time to see if it does any better. Or perhaps I
should also try and set each child control to null in my disposeChildren
function. Perhaps IE would then remove them from memory. I just think IE is
very slow on garbage collection (there are about 100 or more controls in the
tool window each time it gets displayed and some of the controls are
grids/tables.
Thanks for the help,
Jim
