Thanks Chris. That did the trick. Perhaps a quick note could be added to the MEM driver doc page?

I had a near identical issue when upgrading from V1.4.x to V1.5.2. The code checks the name passed in as the "filename" to Create(). ONLY if it is of the form "MEM:::" will it then look for other expected parameters (including PIXELS, LINES and DATAPOINTER). Otherwise, the passed in filename is pretty much ignored. So, the actual answer is to rename "MEM:::" as anything else and you will be fine. Chris Eustace.
