Help solving Bug 434

Hello all,
I'm taking yet another look at bug 434, where a left mouse click won't
release in Visual FoxPro.
Alexandre applied a patch on 6/13/02 that fixed the issue for the opener
of the bug, but is general issue still exists for me, I havn't heard from the
submitter of the Illustrator 8 report.
First question:
Since the original report has been resolved, should a new report be opened?
Second:
I feel like the solution is pretty close, but I'm probably treading water
in deep fog, FEELING like I'm getting close to shore :)
The one weird thing that I can't figure out is why I can run
wine --debugmsg +scroll,+event,+toolbar,+gdi,+heap /mnt/windows/DevStu
dio/vfp/vfp.exe
and have the button up WORK for a few clicks. If I hold the button down, then
release, the issue occurs. Since the mouse issue started when input functions
were moved into the wine server, it makes sense to me that there might be some
issue related to synchro.c as shown below in gdb output.

Ok - ivanovich at menta.net determined the fix for Flash 5 to
be patch at:
http://www.winehq.com/hypermail/wine-cvs/2002/06/0098.html
from 6/14/02.
This patch does not affect the mousebutton issue in Visual FoxPro, but his posts
on using gdb now make sense to me..
Using Wine-20020804.
wine test.exe (using vfp5test.zip - Installer works now!)

Here's my output of GDB:

Here, just like ivanovich at menta.net's post, the gdb hangs and the wine process
takes 100% cpu. If the scheduler is not working properly
with FoxPro, that might explain the weird 'Slowness Solution' I described above,
with extra debug info delaying the button up issue.
If I ctrl-C and detach from that process, and attach to a second wine process,
I get:

Here, just like ivanovich at menta.net's post, the gdb hangs and the wine process
takes 100% cpu.
I tried putting a while loop in synchro.c, so that it would loop until
!(HIWORD(ret)), but I did something wrong:
--- synchro.c line 231
int ret, cookie,testparm;
struct timeval tv;
testparm = 0;
while (testparm == 0){
testparm = 1;
if (count > MAXIMUM_WAIT_OBJECTS)
...
...
if (HIWORD(ret)) /* is it an error code? */
{
SetLastError( RtlNtStatusToDosError(ret) );
ret = WAIT_FAILED;
testparm = 0;
}
}
return ret;
---
I don't know if something like that would actually work, but my last gdb step
through showed testparm set to 0 before returning ret ;) - so I whatever I did,
I didn't do it right.

Any direction to take would be greatly appreciated.
Thanks
