Description Jan Lahoda 2004-04-29 12:21:30 UTC 
NB continuous build 20040428-1330, JDK1.4.2_04.

1. Open a java file with many todos (approx. 1000
in my case).
2. Open the TODO window.
3. (The Current file is selected).
4. Wait untill the TODOs are scanned (this may
take a while).
5. Switch to "Opened Files": the GUI is frozen,
because of some work done in the AWT event
dispatch thread (see attached thread dumps).

Comment 2 Jan Lahoda 2004-04-29 12:43:20 UTC 
To clarify myself: the computation that locks the AWT takes at least
ten seconds. I have only one file, but with approx. 1000 TODOs.

It's worth to address but it's rather scalability test then typical
use case. =>P3
Comment 4 _ pkuzel 2004-05-03 15:18:17 UTC 
The same happens for the current file view.

And I remember why I rewrote from asynchronous, delayed, handling that
caused flicker (500ms delay) to synchronous handling. It improves feel
for most use cases (except stress tests :-).

the tasklist has been completely redesigned, this issue doesn't apply any more
