Maybe it's a clear indication that real compiler updates have been missing for quite some time. No, definitely it is not THAT. You might attempt to promptly purchase Lite-C, or you could try praying that the bmap blitting functions are quick enough to emulate hbars...er windows?

Choose one of the following:
*It's a bug. (not likely; go on, try to get it fixed now)
*It's a 'slack' feature omission. (possible)
*It's a calculated 'marketable' feature omission. (possible)
*None of the following.

To be clear, I'm not absolutely certain that 'global vars' are required for hbars or windows, but based on comparisons elsewhere, I would have expected such requirements.
