I am having a similar problem. My images are 1 MB in size but I need to load 3 sets of 4 so my memory usage is aproaching 300 MB as well. After an hour - 1 1/2 hours windows reports a virtual memory error and the application hangs causeing all sorts of problems.

I have tracked memory usage usint Task manager and have used the C++ Builder 6 Code Guard feature and have found no evidence of a memory leak. (Memory released after processing an image set is consumed by the next set and have seen no gradual increase in memory consumption.)

The systems are all 512MB with 1GB virual memory files on W2K.

If I can't get around this soon I may have to rewrite the program around a different library and I have no desire to do that.

Please help,
