Hi,
I have just encountered a problem in HS Editor using this configuration (link to Editor).
The control buttons sometimes visually disappear (after they have been clicked on by mouse). They are still clickable (displaying its browser-tooltips) but not visible. (Both buttons and control "panel" background are invisible.)
It happened while configuring the Highslide Editor, I didn't test the behaviour of the resulting gallery on a webpage.
I use Opera 9.64 browser, Windows XP Home.
Endigo.
