Original trayicon (16x16 pixel) looks distorted on Windows with desktop Large or Extra Large font size. Large font needs 18x18 pixel, Extra Large 22x22 pixel.
I have added 3 files trayicon.png for each setting in my new skin (users.eurocom.od.ua/~as57/index.htm), but users must correct xml file manually. It is very inconveniently. Is it possible to develop program for automatically using one of such three files?
I enclose screenshot of 18x18 icon (left) and original (Shadow4) on my desktop with Large font setting.

I'm not sure if I can get the pixel size of the tray icon from the framework. I'll have to check this.

If Rainlendar cannot detect desktop font size mode, best solution is manual selection of necessary file in Advansed settings menu. I am glad to propose you to use my files trayicon-N.png, trayicon-L.png and trayicon-EL.png.
