Performance Issue When Removing All Lifelines in All-In-One Sequence Diagram

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Drag-and-Drop "All-in-one" sequence diagram into workspace
2. Delete all lifelines (Leave title in)
3. Maximise/ adjust size of window

What is the expected output? What do you see instead?
Expected: A standard box representing the seq. diag. with a title
Instead: Main window goes a solid grey, strange performance issues

What version of the product are you using? On what operating system?
Umlet v12.0 (February 2013)
Windows 7 Enterprise

Please provide any additional information below.
The error may be recoverable provided you can get the program to refresh and 
redraw the "Diagram selection/Properties" portion of the screen and add a 
lifeline.

umlet threw an exception internally in that case. It should be fixed in v12.1
