Not a question, just something I thought I would pass along. In Windows, 32-bit applications are limited to 2GB of process memory, even in a 64-bit OS (e.g. Windows 7)... Working with large files in XnView (>2MB) gave me trouble getting more than 9 or 10 open at a time; I'd get an out-of-memory popup. The trick is to edit the XnView executable using editbin and the /largeaddressaware switch. This allows the process to access 4GB of memory, letting you open substantially more images at once.
