Relay log

When trying to enter rich text in a drawing in 4m - Ingellicad an endless loop
is encountered (CPU stays 98%). See details below. The console output is
attached.

Wine version: wine-0.9.56
OS: OpenSUSE 10.3
Windows: No windows, just a clean wine install
Program: 4M - Intellicad 6 classic. Download demo:
http://www.4msa.com/downloads/SetupICADClassic64_E.exe
Install: wine SetupICADClassic64_E.exe
How to run: I had to copy mfc71.dll,msvcr71.dll and msvcp71.dll from a Win XP
SP2 install into drive_c/ICAD6CLASSIC folder
  Command line: wine "C:\ICAD6CLASSIC\icad.exe"
How to reproduce:
  Run the program, in welcome dialog click 'Start Evaluation', in program
command line type 'mtext' in command line, drag a rectangle on screen and in
box
that appears type whatever you want (don't worry about black letters on black
background) and click 'OK'. All freezes. 
When started with +relay, the following lines appear endlessly:

0009:Call user32.SendMessageA(00000000,00000150,fffffffe,00000000) ret=00585ec5
0009:Ret  user32.SendMessageA() retval=00000000 ret=00585ec5

Only difference is that the third parameter decreases with 1 every time it is
displayed.
