Undetermined action in Umple Online results in changed cursor position and removed text from text pane

[GoogleCodeExporter]

Description of problem.

When working in the text pane in Umple Online, it is possible to get in a 
situation where the following two things occur:
 1) The position of the cursor is changed to be at the start of the text pane input box.
 2) Some of the recently entered text may be removed from the text pane input box.
It seems that this problem occurs when edits are being done on the page while 
it is also refreshing from the server. Maybe there is a race condition here?

What steps will reproduce the problem?
 * It is unclear how to reproduce the issue consistently right now, but several people have experienced it.

What is the expected output?

The expected output is that the cursor remains where it was placed; i.e., does 
not change position unless a user moves it manually, and that none of the text 
in the text pane is removed without a user doing so themselves.

What is the actual output?

The actual output is that there are cases when seemingly arbitrary pieces of 
text in the text pane are removed and the cursor changes position without input 
from the user.

This may have been fixed, since I haven't encountered it recently and there 
have been lots of changes
