99.1 Known Issues</h3>
<h4>
99.1.1 Wheel Mouse</h4>
SWT does not directly handle the extended messages sent by the wheel mouse.
If the correct driver is installed for the wheel mouse, the extended messages are mapped to
cursor operations that are supported.
<h4>
99.1.2 Available Colors on 8-bit Linux</h4>
Typically, in Gnome Linux installs running with 8 bitplain visuals (i.e. 256 color mode), before the
Eclipse application is started, you already do not have any free colors. This may mean that Eclipse
is unable to allocate the default widget background color causing it to display a white background.
The functionality, however, is not affected.
<h4>
99.1.3 Motif Accelerators</h4>
Keyboard accelerators on motif are sensitive to the state of all modifier keys such as the Caps Lock,
Num Lock and Scroll Lock keys. For example, Ctrl 'S' is not the same as Ctrl 'S' with the Num Lock key on.
If keyboard accelerators appear to not be working, please check the state of all other modifier keys.
<h4>
99.1.4 XInitThreads and Linux</h4>
SWT makes use of the XInitThreads system function to allow graphics routines to
be invoked from non-user-interface threads. However, the implementation of XInitThreads
on Linux has several issues, which cause the following SWT problems:
<dl>
<dt><b>Printing Support</b></dt>
<dd>The X printing extension implementation on Linux currently does not work for applications
which are XInitThreads enabled. This makes it impossible for us to provide printing
support on Linux. Until this is rectified, <code>Printer.getPrinterList()</code> will
always return an empty array on the Linux platform.</dd>
<dt><b>Drag and Drop</b></dt>
<dd>On Motif, SWT only supports dragging between windows running on the same system process.
In particular, dragging a file between Eclipse and another application will cause the
drop target application to hang. This is a result of a bug in the Motif libraries for
applications that are running XInitThreads.</dd>
<dt><b>IME Support</b></dt>
<dd>The Japanese IME support provided by Linux is currently incompatible with applications
which are XInitThreads enabled, and will cause them to hang.</dd>
</dl>
<h4>
99.1.5 Disposing in a Focus Event</h4>
Applications should not dispose widgets in focus changing events. Doing so on Motif may cause Eclipse to terminate,
since Motif accesses the disposed widget within their internal focus change event handler.
Similar but less serious issues exist on Windows such that occasionally an SWT exception can be thrown.
<h4>
99.1.6 List and ComboBox on Windows NT</h4>
On Windows NT only, you should avoid creating items in a List or ComboBox with strings longer than 1000 characters.
Doing so may result in a General Protection Fault. This has been fixed in more recent versions of Windows.
<h4>
99.1.7 BiDi Support</h4>
The StyledText widget now provides bidirectional language support for Hebrew and Arabic locales.
Currently, this support is available only on win32, and has several known problems. It should be
considered to be a preliminary implementation only.
