Yet more information, I tried running it under 2.6.6.152 (using
the older screen rectangle command syntax) and I got it to export

memory, so the problem must have been introduced in version 2.7.x.
FWIW, last night I experienced crashes in one of my apps built with
v2.8 that has never crashes before. This app is different from
most others I work on mainly because of the number and frequency of
file-writing operations. There may be a connection to what you're
seeing, or something else. If I find a pattern I'll get back to you.
I can't see that this could have been tested past a cursory
glance before releasing it.
While RunRev has had a history of some of the shorted Beta cycles
I've ever seen, in this case the time between v2.6 and the current
v2.8 spans more than a year and during most of that time this issue
eluded a recipe. That this is being seen now and a recipe is being
honed in on is a good thing, but I'd hate to see RunRev err too far
the other direction with Beta cycles extending longer than a year.
Some bugs are not immediately evident, and will take time to
discover amidst the nearly infinite combination of tokens that can
be executed.
All I know is that if I were to write something like this (a file/
image data exporter) then once I'd got it working past the the point
where I could write an image file in all the different formats then
I'd run a soak test on it and let it run for *loads* of (like 10,000
+) of iterations and I would have checked that memory was being
released. In fact I wrote an external command module that does
something similar (it analyzes movie frames) and I *did* soak test it
and I *did* find memory leaks.
For me, this is software engineering 101.
All the Best
