sryo: nope, in fullscreen the litestep-based windows don't flash, only when it's in normal viewing mode.

doy, that's pretty weird.. The only issue I've had with opera occurs when I've set the window to be transparent using lstransparent.dll and I go back (previous page) on some litestep.net pages. Basically the page just doesn't re-display, it stays as the page I was just looking at, except maybe hilites the link I had clicked on.. Only on some litestep.net pages, like forum pages and theme description pages.. but I figure that's a problem with Opera not lstransparent.dll

Anyway, hope this thread is of usefulness to systray2 dev's :)
