P.S. Problem with X11 driver

[Till Mossakowski]

Hi,

I have found (part of) the cause of my deadlock problem with the X11 driver.

Wine gets stuck in the function X11DRV_IsClipboardFormatAvailable in
dlls/x11drv/clipboard.c. I have appended the corresponding backtrace
below.

When I replace this function by a function returning constantly FALSE,
my programs runs without any problem.

Of course, this only is a workaround. Is there any malfunction to be
expected by this workaround?

I do not have the expertise to go deeper into the X11 driver internals
to find a real solution.

Is there a more detailed documentation for the X11 driver?
In the wine documentation pages, on the page x11drv.html it is
said that this has been extracted from wine/documentation/x11drv.
But I could not find this in the CVS repository.
