Im using illusions theme, and my systray icons have pinkish border around them, plus when i maximize my window they dont fully maximize, they have like a strip of transparent border.
Any info that could help me fix this is greaty appreciated.

i don't know illusions, but try updating the systray module to the latest version. or if it doesn't use any background image, use magic pink as the background colour.

about the window size, look for a desktoparea setting (depends on whether you use desktop2 or jdesk).

the pink border around the tray icons might be becasue it's using magic pink as a bg, try setting an image or another color and the bg.

That transparent border is from the window border. It is probably around 4 pixels if you are using the windows classic appearance. You may just need to change the desktop area.

The pink border around soome of the systray icons is specific to WinXP. Some icons in WinXP will use per-pixel-alpha for anti-aliasing and dropshadows and whatnot. Systray doesn't really handle it well, neither does vtray.

if you want your windows to fully maximise, go to line 72 or so and look for this line

jDeskWorkArea "5,5,-5,-5"

and change all four numbers to 0.
