            Bug ID: 47254
           Summary: Unhandled exception: page fault on write access in
                    32-bit code
           Product: Wine

Back trace dump from Wine crash.

Used to run Legacy9 (genealogy software). Mostly runs Ok. But, there are
latency issues There is a problem with buffering keyboard input characters. If
you select an input field and start typing too fast, the first two characters
will generally be ignored. There also seem to be issues with background
processes where after changing windows you need to wait 4-6 seconds before
input keystrokes are accepted (they are also not buffered).

Randomly, the system will display a message box about "the system has
experienced  a serious error..." and a crash dump is displayed: "Unhandled
exception: page fault on write access to 0x6d4a95c8 in 32-bit code
(0x7b476e81)." The message box allows a backtrace dump to be saved. 

The Legacy9 program is then locked on the last display screen and is
un-responsive to keyboard or mouse clicks, although the mouse pointer is still
active. The computer itself is not locked up. Closing the program error message
box also closes the Legacy9 application. The Legacy9 application can be
restarted at that time.
