Memory Leak on export png????

[Dave]

Hi,

Some more information on this.

If I delete the Text counter object from the group that gets exported  
the it will output many more images (once it actually did all 500)  
before stopping. Doing this it will just continue forever, e.g. Most  
of the time I don't get the error dialog and mouseUp handler never  
exits.

I looked at the system activity monitor and found that 1.68 GB OUT of  
my 2 GB was allocated to RunRev, so I guess it really is leaking!

I also tried storing the image into a variable instead of a file and  
get the same problems.

Not sure what else to try? Would be interesting to find out why it  
works on your system and not mine or Ian's. Anyone what to try this  
on their system? Haven't tried this at all under Windows.

Thanks a lot and All the Best
Dave

Ok, are you using the standard RunRev IDE and not running anything  
other that the standard RunRev stuff?

I set the fill color via the Property Inspector, not via a script,  
not sure if that would make a difference. I have removed all fill  
colors and I still get the error when writing file number 289. I've  
also tried making the object/rectangle smaller, still stops on file 289.

Then I tried adding a wait .25 seconds after the export operation,  
same problem.

I then replaced the repeat statement like this:

   repeat with x =  (1 + 288 to (tNum + 288)

And it still gave an error on 289!

I then tried (300) to (tNum + 300) and got the error on file 608!
Then 290 to (tNum  + 290), the error occurred on file 298.

This is very strange problem! It happens every time on my system and  
Ian appears to have had the same problem too. would be good to track  
why it works ok on yours.

All the Best
Dave
