I have an application that creates a ToolBar and the creates a single
ToolItem on it.

When the application is running.. tooltip text is displaying properly when I
hover the cursor over the ToolItem.

Once I click on the ToolItem.. tooltip fails to display any more.. .even if
I move the cursor off of the ToolItem and back on to it.

I am setting the size of the ToolBar based on a call to compute size..

Like this..
ToolBar toolbar = new ToolBar(<some composite?, SWT.NONE);

ToolItem popupItem = new ToolItem(toolbar, SWT.PUSH | SWT.FLAT);
popupItem.setImage(<someimage>);
popupItem.setToolTipText("some tooltip text");
Point pt = _datePickerPopupButton.computeSize(SWT.DEFAULT,
SWT.DEFAULT, true);
toolbar.setSize(pt);

I have found that if I increment the size by 1 pixel in each dimension.. the
tooltip text works correctly, even after I click on the ToolItem

Is this a know bug or am I doing something completely wrong here?

Sounds like a Windows bug. Enter a problem report and we can try and work
around it.

I have noticed the same problem since some time. I think I first saw it
in some early 3.0 Milestone.
Not sure if there isn't already a bug report opened on it.

Actually... after a little more digging.. I am now convinced it's a XP
issue...

Was trying to write a simple example that reproduced the problem but was
having no luck.. What threw me off was that my application uses the XP theme
(that is, my application's JRE has the javaw.exe.manifest file setup as
described in another post to this group)...

But.. my eclipse IDE that I use for examples and play is not using the XP
theme...

You can reproduce the problem in eclipse (if using XP theme) by hovering
over any toobar that has only 1 tool item..
Hover over it long enough so that the hover text appears.. then subsequently
disappears (about 5 seconds or so?)
Move the mouse off the toolbar and then back on.... no tool tip text is
displayed...

By the way.. you can reproduce this on Windows explorer too (again.. on an
XP system).

Just hover over the green "Go" button and wait for hover text to appear and
the disappear.. move off the button, then back on.. no hover text.

My comments below about the problem being related to setting the size of the
toolbar has nothing to do with the problem.
