Re:	Bug in CorelDraw! 3.0b

	Corel V. 3.0 rev. b has the following bug:

	If you resize a large number of ungrouped objects, 
you will suffer the loss of a substantial portion of the 
GDI heap (system resources) which is allocated and never
freed.  When you exit the program, the GDI heap memory 
can only be recovered by restarting Windows.

	A little snooping in the GDI heap reveals the 
following:
                  Before   Load    Load  Resize    Exit
Objects:          load     Prog.   Dwg.  54 objs.  Prog.
free               22       28      31    21        22
moveable          147      279     280   338       210
fixed               7       12      12    13        13
total allocated   154      291     292   351       223

% free             77       68      68    62        70

	You can continue resizing until the GDI heap free 
space drops to 0, which will wedge Windows.  Hope you 
didn't need that drawing.

	I called Corel about it, and they stonewalled a 
little ("Oh, we never hear problems like that..."), then
when I spoke to a senior tech rep ("Rick"), he admitted 
that this was a known bug, and unlikely to be fixed in this
release of the software.  He said it was worse with Windows 
3.0.

	If you group the objects BEFORE resizing them, then
the problem goes away, viz:
            
              Before  Load   Load  Group   Resize
Objects:      Load    Prog   Dwg.  Objs.   Group   Exit 
free           27      18     17    14      17      18
moveable      147     280    280   281     281     153
fixed           7      12     12    12      12      12
total alloc.  154     292    292   293     293     165

% free         77      68     68    68      68      75

	Still not perfect on freeing allocated GDI heap, 
but much better.

	If you have been experiencing peculiar behavior, 
such as "out of memory" bitches with plenty of free memory,
Pallette or rollup icons that go blank, or unexpected 
crashes, this may be causing it.

	I won't get into the philosophical aspects 
of Corel selling software with bugs this major.
