Hi Wojtek,

I managed to crash BB 1.3 some time ago. I updated the
log file with continous writes during a Monte-Carlo
simulation and apparently the writing through the
windows API produced a memory leak. It wass allocating
heavily and continously memory until Windows started
thrashing and was unusable.

OM was not very interested to trace that error down ...

A hint: Set Edit->Properties->"Status Bar" to double
and it will inform you about the currently allocated
memory. If this is steadily increasing but still
well below the physical memory, you normally can
do a Ctrl-Break to get a trap viewer ...
