Hi Michael,

Unfortunatley its difficult for me to tell customers and users they have to change operating platforms :)

The way Ive written one of the modules in our application is that it imports the photos from a digital camera and stores them all on the local disk drive. The preview-window only shows 4 photos at a time (during the import process it generates a low-res preview copy of the primary image). As the user scrolls back and forth thru the previews it flashes the photos on and off disk so there are only every 4 low res, and 1 hi-res photo being displayed.

Ive run tests importing 100 640x480 photos - importing, processing and then saving to disk. This works okay about 7 times before the CreateDIB error shows up.

I then try it using 9 hi-res (2048x1564) images and it failes the 1st time around ...

Ive checked the code and everything Im freeing everything as required ... within the form there are 5-6 instances of the ImageScrollBox and thats it ...

Has anybody else found a solution to this problem ???
