Does it still happen if you remove the visual effect?

Hello folks,
I am hesitant to call this a memory leak problem, but it doesn’t seem far off.
I have a group consisting of an array of 18x 5 button radio buttons, each set
prepended by a field labelling the scale.
All the buttons, and label fields contain a custom property (csplain)
consisting of explanatory text/advice. This appears as a multiline tooltip
style field if the mouse lingers within the object for more than 500ms.
The delay is created by a send in time message (‘stillin') triggered by
mouseenter. The ’stillin’ script is:
on stillin
global gtarget
if the mouseloc is not within the rect of gtarget then
hide field “splain"
exit to top
end if
- - Bails if mouse pointer has moved out of object in < .5 sec
if the first word of gtarget is "field" then set the textcolor of gtarget
to red
- - if a field then -> red text
put the csplain of gtarget into field "splain"
set the height of field "splain" to the formattedHeight of field “splain"
set the topleft of field "splain" to the topright of gtarget
put (height of this stack -the bottom of field splain) into toffset
if toffset < 0
- - Check if splain extends off screen. If it does, shift up.
then
get the loc of field splain
put (item 2 of it+toffset - 10) into item 2 of it
set the loc of field splain to it
end if
show field "splain" with visual effect wipe down very fast
end stillin
Some of the explanatory csplain text is very brief, some maybe 50 or 60 words.
An example is:
“This is an important scale for the Non-Psychotic Supercluster (Especially in the
absence of 'Other mental & behavioural problems' (item 8))
* Do not include over-activity or agitation, rated at Scale 1
* Do not include suicidal ideation or attempts, rated at Scale 2
* Do not include delusions or hallucinations, rated at Scale 6”
I first noticed something odd when I ran a quick test in a minimally specced
Windows in VM. I noodled about looking at the text appearing and disappearing as
it should, when the standalone crashed. I ran it on a physical machine, and it
didn’t crash under Win 7 or Vista, but I did notice the memory allocation
embiggening with most, but not all, appearances of the tool tip - between .2 &
.7 MB a time. The memory was never released when left alone or navigated to
another stack.
I then discovered the same thing happening on Mac with standalone, and in the
dev environment.
I created a test stack with nothing but 6 buttons in a group containing the
same script. Nothing happened. Well, nothing happened that shouldn’t happen.
Any suggestions about what might be going on here?
Best wishes,
David Glasgow
