Thanks flomotan, Zoom function did work when I open back the “Navigator Palette” in CS2
But I think it still got problems.
In PhotoShop CS2 the Navigator Palette will automatically adjust by the ratio of the artwork, and most of the time the Navigator Palette will become bigger and will overlap with other Palette, even after I adjust the Palette size back manually, this situation won’t cause any problem in CS or un-plug your device.
But when running SpaceNavigator with CS2 the Navigator Palette will go behind and overlap with other Palette instead of go front of other Palette like your plug-in dose in CS.
After that happened the Red Fame will just mass up and after several times of changing between Palettes, sometimes it will cause PhotoShop and even whole the system crash.
And I found that Zoom Function work well even when the Navigator Palette is close in CS.
Also, I think to keep the Zoom Function work well without Navigator Palette on is more logically correct.
Especially when you release the plug-in for Illustrator.
When using Illustrator on large size artworks, designers sometimes will have to close the Navigator Palette to keep better performance. So, I don’t think that will work if the Navigator Palette still have to be opened in those cases.
I also post some words for requesting the support for more adobe software viewtopic.php?t=167
hope you can take a look.
