           Summary: DDE problems with TWAIN app
           Product: Wine
           Version: 20040716
          Platform: PC
               URL: http://www.scanace.com
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-ipc
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: brainstorm(a)menta.net


I own a scanner (pacific image scanace 630p (parallel port scanner)). It comes 
with specific software (Cyberview, 
http://www.scanace.com/download/drv_630p.htm). I also use DeskScan as the 
program to launch Cyberview (http://www.snapfiles.com/get/deskscan.html). 
 
The problem is DDE, nothing is shown, the app (Deskscan) just hangs with no 
CPU overhead when I issue an "Acquire" from the "scan" menu: 
 
~ $ WINEDEBUG=+dde,+relay wine .wine/fake_windows/Program\ 
Files/DeskScan/DeskScan.exe 
 
err:win:WIN_FindWndPtr window 0x1003c belongs to other process 
err:ddeml:DdeConnect Done with INITIATE, but no Server window available 
 
The state of the scanner is not relevant, it's just a dde emulation fault (the 
same results are archieved with scanner connected & disconnected). In other 
words, the error is fully REPRODUCIBLE.
