[Wine] Problem with text entry fields (Mac OS X Snow leopard)

[monochromevision]

I use Wine for the windows programs I created with Clarion (Topspeed) environment. After upgrade from Mac OS X Tiger to Snow Leopard, I can't input any text in entry fields, using English keyboard layout. When I type something, I hear the beep sound, no letters appers on the screen. I even can't paste latin letters text using shortcuts, and the context dropdown menu doesn't appear anymore. However, russian keyboard layout works fine. I can type when I switch to russian keyboard layout. Also, this problem is only for the single line entry fields. The multi-lined textareas are working ok.
Please help if you have any suggestions. Thanks in advance!
