TVRD() with 1024 x 1024 window: IDL or MacX 1.5 problem? [message #5506]

I'm using IDL 4.0.1a on a DEC Alpha running OpenVMS, and using a
PowerMac 9500/132 with a PCI display card at 1200 x 1600 resolution to be
able to display 1024 x 1024 images without chopping off the top 46 rows
(take a look at !d.y_vsize on a ysize = 1024 window on a 1024 x 1280
display). Everything works OK except for TVRD --- either with explicit
arguments or just as TVRD(), it messes up the read-back image
significantly.

Has anybody else with a large display seen this sort of problem, or am
I simply guilty of the ultimate crime of the '90's: not using an OS whose
name begins with either Windows or th eletter "u?"

Actually, I'm willing to believe it's Apple's Open Transport 1.0.8, or
their Ethernet driver from all the horror stories I've heard, but I'd be
interested in any other stories.

Thanks,

Joe Gurman
