Is that the only change that was made.  I would be surprised if that was 
what caused your problem. (but I am regularly surprised)

That's the design when -dialogui is used for a multi-line textfield (or 
RichEdit) control under windows.  When this is the case Windows 'steals' 
<ENTER> to activate the default button on the dialog, and to get an 
'\r\n' sequence in the textfield you must <CTRL-ENTER>.

There is a was to change this behaviour:  add
   -addstyle => ES_WANTRETURN,
to your Textfield constructor (ES_WANTRETURN takes the value 4096).

This allows the Textfield to 'steal' the <ENTER> back, but <ENTER> will 
no longer activate the default button while the textfield has focus.

[In the next version of Win32::GUI there will be a '-wantreturn' option
for Textfields/RichEdit controls, as I've lost track of the number of 
times I've seen this question on this list - I guess I should also make 
it a FAQ]
