HexDump Data Entry Not Functioning

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create new stream.
2. Edit new stream. Then at Protocol Selection Tab set Payload selection to Hex 
Dump.
3. Go to Protocol Data Tab and select HexDump section. Place curser in HexDump 
text/data area. Curser does not respond to keyed number entry. 
4. After many attempts data may be entered. No consistent way to make data 
entry work.

What is the expected output? What do you see instead? I expect to see the data 
I type show up in the HexDump definition area.


What version and revision of the product are you using (available in the
About dialog)? On what operating system? Version 0.5.1, Revision 74c9dcf830e3@. 
Windows XP and 2000.
