- The Win32S subsystem was the clincher... these are 32 bit extensions of
- Windows. I suggest you take a close look at your pointers and check whether
- they are processed correctly within the 64k segment limit. They might work
- perfectly on 32bit platforms and then cause problems on non-16bit
- platforms.. :( Having said that from experience of problems with large
- bitmaps in 16bit Windows.... (Try using huge pointers and GlobalAlloc/Lock
- etc)
