It's not something critical and I do not know where else to ask.
But whenever I draw in chibipaint/java and go to fullscreen mode, in the bottomright corner are numbers.

The ones down there now are:

Mem: 102,9/121,8,D57,3 U9,4

They're coloured red now.
But what does it mean? Does it have anything to do with the computer memory? It changes over time (when I draw, add new layer etc.)

Mick, or anyone else here , can you tell me what it means?
I'm curious and if it has anything to do with computer memory then it might be useful to me, since I often have fights with my computer memory and java.
