Greetings Philippe,

Given the fact that this bug seems to have mysteriously started to happen,
and the comment about a timing issue in the source for
PlotWindow.windowActivated, I suspect that there is a some sort of a race
condition going on. My plugin ran did not have the aformetioned plotwindow
problem for the past year or two on linux and windows. I ran into this
same problem ages ago on the Mac and was told there was no known solution.
 Since I found a partial solution, I thought I would share, in case
someone else runs into the same issue.

There also seems to be a race condition with zooming an imagewindow.  The
OS/windowmanager window generally results in the correct size, although,
sometimes/often the image in this window was left in a partially zoomed
state.  Calling imp.getWindow().getCanvas().fitToWindow(); after xooming
seems to get the zoom to complete consistently.

And the imp.getWindow().getSize(); sometimes returns a width that is a few
pixels to wide.

Fred
