Hello,

RAP-Version:
1.4SR1

Perequisites:
- use IRunnableWithProgress in an ApplicationWindow
- a progress will be executed by a SelectionListener of a "Text"-control

See my example to reproduce.

Description for my example:
Type in some text in the "Text"-control and press enter key. Now the progress will be started and will end after 2.5 seconds.

According to the java-source now the following should happen:

// It's necessary to restore focus after reenabling the controls
// because disabling them causes focus to jump elsewhere.
// Use forceFocus rather than setFocus to avoid SWT's
// search for children which can take focus, so focus
// ends up back on the actual control that previously had it.
currentFocus.forceFocus();

For Firefox and Internet Explorer i have found different behaviors after pressing enter key which will be described in the following:

Firefox 8.0:
The cursor is visible and it is possible to edit the text of the Text-control by keyboard.
If you try to use the mouse cursor to mark some text you can see that this is not possible. Only in the case that you explicit reset the focus by clicking elsewhere and then back to the text-control you are able to mark some text.
Next thing which is curious is the fact that you have to press enter key two times to start the progress a second time.

Internet Explorer 8:
The cursor is not visible but you are able to press enter one time to restart the progress again. However, editing text is NOT possible.

Steffen,

from reading your post, this looks like browser quirks. Did you try and
see how Chrome/Safari behave?
In any case, would you mind to file a bugzilla [1]? With a bug report it
is easier to track this issue.

Regards,
Rüdiger
