After applying a screen filter, the gui disappears and the app then sits in the taskbar minimised at the bottom of the screen. I can't maximise S4W to bring up the gui again when I need to change the effect or close the program.
As I can't maximise it, after using S4W I need to force close it using Control Alt Del (task manager). I can right click to ''close window'' to remove the minimised S4W that is stuck on the taskbar, and although this makes it disappear it still runs in the background as a process. I wasn't sure if it was a bug or just my computer.
To be able to have the program minimised next to the clock and date after applying an effect though would be good in future, with it's gui easily brought up (perhaps by using a keyboard shortcut). Thanks!
