Strange error (not enought memory)

A short story:

The boss of The Company (we name him P. Charles) instructs two employees (Tom and Jerry) to give him an overview about the current financial situation about the company.
Both walk into a meeting room and they comb through company records to compile the numbers which they write on the white board.
In the meantime P. Charles instruct another employee (named Oliver) to explain the story about the flowers and the bees to a further employee (named Stan).
Working for while Tom and Jerry decides to make a lunch break, and leave the meeting room.
Oliver and Stan are entering the now empty meeting room. Oliver cleans the white board and draws some nice sketches from flowers and bees. After a while Stan understand how the game works between the flowers and the bees, and both leave the meeting room again.
Again after a while Tom and Jerry go back to the meeting room, finding the strange drawing on the white board.
They could not understand why the white board now shows different things.
They go to P Charles and telling him that the white board seems to be broken, because the numbers on the white board has changed to some strange drawings.

P. Charles now asks all the other employees whether they observed such a strange thing with the white board.
Stan and Oliver respond to the boss that they swear everything was alright with the white board some minutes ago.
They could write to the white board and nothing unforeseen happend to the drawings.

I don’t now whether this happened in such a way.
Believe it or not.

Very interesting story!

The second problem was solved!
I just replaced LV_EVENT_CLICKED with LV_EVENT_VALUE_CHANGED and now everything goes ok.
