BUG: Combo Boxes in DS_SYSMODAL Dialog Boxes:
Q74507BUG: Combo Boxes in DS_SYSMODAL Dialog Boxes
When a combo box with the CBS_DROPDOWN or CBS_DROPDOWNLIST style is used inside a
system modal dialog box, it causes the following problem in Windows versions 3.0
and 3.1:
An item cannot be selected from the drop-down list box by clicking it with
the mouse. The original selection remains in the edit control or static-text
control.
Using a combo box with the CBS_DROPDOWN or CBS_DROPDOWNLIST style within a system
modal dialog box in Windows version 3.0 causes the following problems:
1. The drop-down list box cannot be closed by clicking on a part of the list box
that lies outside the dialog box.
2. The parts of the drop-down list box that lie outside the dialog box are not
erased when the drop-down list box is closed.

In version 3.4 of the PostScript printer driver, when the DC_PAPERSIZE index is
specified in the DeviceCapabilities function, the width of the paper is returned
for both the x and y coordinates in each POINT structure. This function should
return the height and width of each supported paper size.
===============================================================================
BUG: Protected-Mode GlobalCompact() Return Not Free Memory:
Q76686BUG: Protected-Mode GlobalCompact() Return Not Free Memory
When Windows is running in one of its protected modes, the value returned by the
GlobalCompact() API does not accurately reflect the amount of free memory
available in the system.
In enhanced mode, Windows can swap memory objects to disk. This process takes a
long time relative to accessing an object in memory. Therefore, GlobalCompact()
returns the amount of memory available without performing any paging.
In standard mode, GlobalCompact() never reports more than 1 megabyte (MB) of
memory free because of a memory allocation limit on the 80286 chip.
===============================================================================

address of the memory block can change.
===============================================================================
BUG: GetModuleFileName Returns Relative File Path:
Q85330BUG: GetModuleFileName Returns Relative File Path
When the GetModuleFileName() function returns a reference to a dynamic-link
library (DLL) file, the reference is relative (not fully qualified) under the
following circumstances:
- One of the directory references in the MS-DOS PATH environment variable is
relative. Assume that the relative directory reference refers to drive X.
- An application is implicitly linked to a DLL. The DLL is installed in the
current (default) directory of drive X.
- The application is installed in a directory other than the one in which the
DLL is installed.
===============================================================================

Q85596BUG: SETCOLORTABLE Escape Disables Dithering
When the VGAPAL video driver is installed on a system, once an application calls
the SETCOLORTABLE escape to change an entry in the color table associated with a
device context, Windows does not create any dithered brushes for that device
context. Instead, Windows returns the solid brush that most closely matches the
requested color.
===============================================================================
BUG: GetGlyphOutline Returns Blank Bitmap:
Q85598BUG: GetGlyphOutline Returns Blank Bitmap
In the Microsoft Windows graphical environment, when an application calls the
GetGlyphOutline() function to retrieve the bitmap for a glyph and the lpmat2
parameter points to a matrix that magnifies the glyph, a blank bitmap is
returned.
===============================================================================
