I used to have this problem in Bibble 5 too..
When looking through folders, with lots of images, I now an then get a popup that says "Bibble is unable to allocate more memory and will now quit" And obviously they haven't changed the error message since the change of the name.
I'm now running Debian GNU/Linux 64bit with 12Gb of RAM and in no way is Bibble/ASP out of memory...
Anybody else get this error and do you know what causes it? How to fix it?
